Holland America’s Project Evolution is officially moving from just a press release to “here’s a deck plan to look at,” and today we’re getting our first look at just how massive an undertaking this is by checking out the first ship to go under the knife, Oosterdam.
On May 6, 2026, when bookings opened for Oosterdam’s post-drydock sailings, Holland America rolled out the ship’s updated deck plans. These are not the full, final, every-bar-and-bathroom-revealed plans yet. For now, what we have is a stateroom-focused look at the ship after her Project Evolution drydock. But even with that limited view, one thing is already very clear: this is not a light refresh.
This is a major transformation.
Project Evolution is Holland America’s big modernization program, and Oosterdam is giving us the first peek at what that means for one of the line’s older ships. Since the public-space details have not been fully released yet, we still do not know exactly what is happening to every lounge, bar, restaurant, spa area, service desk, or activity space. But the stateroom plans tell a pretty big story on their own.
And that story is: Holland America has been busy.
We went deck by deck through the current Oosterdam deck plans and compared them against the first post-drydock plans. Some decks are mostly category cleanup, with cabins staying where they are but being renamed, reclassified, or moved into Holland America’s newer category structure. That means some rooms may be sold differently after the drydock, which usually means Holland America has found new ways to sell the same rooms with added revenue potential.
Other decks show much bigger changes. We can see areas where new staterooms are being added, where existing suites are being replaced with smaller cabins, where public-facing spaces appear to be giving way to new accommodations, and where the much-anticipated solo staterooms are finally starting to show up. Decks like 1, 8, 9, and 11 especially give us a first glimpse at just how much work is going into this transformation.
There is also a lot of category reshuffling happening. Old familiar categories are being replaced by new ones, suites are being moved into different classifications, verandah rooms are being split into new buckets, and Holland America is clearly cleaning up how it wants to sell staterooms going forward.
A quick note before we dive in: this was a very labor-intensive comparison. Every effort has been made to compare the current and future plans as accurately as possible, deck by deck, but with this much information to review, there may be an error or two.
Also, because Holland America has not yet released the full public-space deck plans, we are only looking at what the stateroom plans tell us. In some cases, it is obvious that a public area is no longer shown where it exists today. In other cases, we can see new staterooms but cannot yet say exactly what nearby public or crew space may have been moved, reduced, or reworked.
When Holland America releases the next version of the Oosterdam deck plans, especially the ones showing the public spaces in full detail, we will do another deep dive. For now, this first look gives us a pretty fascinating preview of what Project Evolution really means for Oosterdam, and it is a lot more than new carpet and some fresh throw pillows.

Deck 1 – Main Deck Stateroom Changes
Current plan: Staterooms 1001-1131 | New plan: Staterooms 1001-1147
Deck 1 is where Oosterdam’s post-Project Evolution stateroom changes start showing up in a very obvious way. Holland America is adding a noticeable block of new cabins at the aft end of the Main Deck.
The big change is that the area currently used for Guest Services, Future Cruises, and part of the lower atrium/public-service space is being converted into additional passenger staterooms. Since Holland America’s new post-drydock plan only shows staterooms and not public spaces, we do not yet know where Guest Services and Future Cruises are being relocated.
Deck 1 Count Summary
| Version | Room Range Shown | Total Staterooms |
|---|---|---|
| Current Deck Plan | 1001-1131 | 130 |
| Post-Project Evolution Deck Plan | 1001-1147 | 146 |
| Net Change | Additional aft staterooms added | +16 |
What Was Removed To Make Room?
The new rooms on Deck 1 come from the area currently occupied by Guest Services, Future Cruises, and part of the lower atrium/public-service area. That is an important distinction because this is not just Holland America filling in some random blank space on the deck plan. This looks like a real reworking of a public-facing part of the ship.

| IC | Interior, as labeled on plan | 1 |
Note: Stateroom 1096 is labeled IC1096 on the new Deck 1 plan even though the Deck 1 legend only highlights IB under interior staterooms.
What Actually Changed?
Most of Deck 1 is a category reshuffle. The current plan uses older categories like C, D, DD, E, F, J, and K. The new plan moves Deck 1 into Holland America’s updated category structure with OA, OB, OD, IB, and one IC stateroom.
The forward oceanview cabins that are currently F become OD. Many of the D cabins are split between OD and OA, while a couple become OB and one becomes IC. The current C cabins become OA. The current DD cabins become OB. Most of the E cabins become OB, with one becoming IB. The J interiors become IB, and the K interiors mostly become IB, although several aft K rooms appear to become OB under the new layout.
The bigger story is aft, where the ship gains 16 rooms and also hints at a much larger public-space shuffle that Holland America has not fully revealed yet.

New Rooms Added On Deck 1
These are the room numbers that do not appear on the current Deck 1 plan but do appear on the new post-Project Evolution plan:
OB oceanview additions: 1130, 1133, 1134, 1136, 1137, 1138, 1140, 1141, 1142, 1143, 1144, 1145, 1147
IB interior additions: 1132, 1135, 1139
Deck 4 – Upper Promenade Deck Stateroom Changes
Current plan: Staterooms 4001-4185 | New plan: Staterooms 4001-4185
Deck 4 is a very different story from Deck 1. There are no new stateroom numbers added here, and there do not appear to be any staterooms removed. The current plan and the post-Project Evolution plan both show the same range of cabins, running from 4001 through 4185.
So what changed? The categories. A lot of them. Deck 4 gets a pretty aggressive category cleanup, especially in the obstructed and partial oceanview cabins, the forward verandah cabins, and the aft-facing verandah cabins. The room numbers stay the same, but the way Holland America is selling many of these rooms changes quite a bit.
Deck 4 Count Summary
| Version | Room Range Shown | Total Staterooms |
|---|---|---|
| Current Deck Plan | 4001-4185 | 183 |
| Post-Project Evolution Deck Plan | 4001-4185 | 183 |
| Net Change | No staterooms added or removed | 0 |
What Was Removed To Make Room?
Nothing appears to have been removed on Deck 4. Unlike Deck 1, where new rooms are being added in space currently used by public-service areas, Deck 4 keeps the same stateroom footprint. The changes here are category changes, not physical cabin additions.

| IF | Interior | 8 |
What Actually Changed?
Deck 4 is basically a big recategorization exercise. The ship is not gaining rooms here, but plenty of cabins are moving into Holland America’s newer category structure.
The biggest shift is with the obstructed-view cabins. The current H and HH ocean-view cabins become IA on the new plan. That is a big category change because the new legend describes IA as an obstructed-view category under the interior stateroom section. So if you are used to seeing those Deck 4 obstructed rooms sold as ocean-view categories, that appears to be changing.
The partial ocean-view G cabins become OG, which is a much cleaner naming convention. The two D ocean-view cabins, 4121 and 4122, become OA.
The verandah cabins also get shuffled. The old VH cabins become VX. The old VF cabins become VH. The old VE cabins become VF. A large chunk of the old VB cabins become VD, while the old VC cabins split between VD and VE.
The aft end is the part to watch. The two current SB Neptune Suites, 4180 and 4185, become NS under the new category structure. Several aft-facing VB cabins also change categories, with four becoming TS Vista Suites and two becoming VS verandah staterooms. Same real estate, different way of packaging and selling it.

Rooms Added Or Removed On Deck 4
No new room numbers appear on Deck 4, and no existing room numbers disappear. The current and new plans both show 183 staterooms from 4001 through 4185. The changes are all category changes, not stateroom additions.
Deck 5 – Verandah Deck Stateroom Changes
Current plan: Staterooms 5001-5191 | New plan: Staterooms 5001-5191
Deck 5 is another deck where the room numbers themselves stay put. Holland America is not adding new staterooms here, and it does not appear to be removing any existing rooms. The current plan and the post-Project Evolution plan both show the same stateroom range, running from 5001 through 5191.
But just because the walls are not moving does not mean nothing is happening. Deck 5 gets a fairly major category cleanup, especially forward and aft. The old category structure with SB, SY, VA, VB, VC, K, and L is being replaced with the new structure that includes NS, GC, TS, VS, VA, VB, VC, VD, VE, ID, and IE.
Deck 5 Count Summary
| Version | Room Range Shown | Total Staterooms |
|---|---|---|
| Current Deck Plan | 5001-5191 | 187 |
| Post-Project Evolution Deck Plan | 5001-5191 | 187 |
| Net Change | No staterooms added or removed | 0 |
What Was Removed To Make Room?
Nothing appears to have been removed on Deck 5 to make room for additional staterooms. Unlike Deck 1, where new cabins appear to take over the current Guest Services and Future Cruises area, Deck 5 keeps the same stateroom footprint. The changes here are category changes, not physical additions.
Current Deck 5 Categories

| VD | Verandah | 6 |
| VE | Verandah | 32 |
| ID | Interior | 8 |
| IE | Interior | 11 |
What Actually Changed?
Deck 5 is almost entirely a category reshuffle. The forward Signature Suites, currently SY5001 and SY5002, become GC5001 and GC5002 under the new plan. The two aft Neptune Suites, currently SB5190 and SB5191, become NS5190 and NS5191.
The forward verandah cabins get cleaned up in a big way. A small group of current VB cabins near the front becomes VD. The forward VC cabins become VE. Then the run of current VB cabins farther aft in the forward section becomes VC. Same rooms, but Holland America is sliding them into a different selling structure.
Midship is a little quieter. Most of the current VA cabins stay VA, but four of them move into the new VB category. Those appear to be the rooms around the midship elevator/stair area: 5095, 5097, 5098, and 5100.
Aft is where things get more interesting. The aft-side VB cabins become VC, while the aft-side VC cabins become VE. The interior cabins in that same aft area shift into the new ID category.
The aft-facing cabins also get a new treatment. The two current SB Neptune Suites become NS. The current aft-facing VB cabins 5184, 5185, 5186, and 5187 become TS Vista Suites, while 5188 and 5189 become VS verandah staterooms. So while the room count does not change, the aft of Deck 5 is definitely being repositioned.

Rooms Added Or Removed On Deck 5
No new room numbers appear on Deck 5, and no existing room numbers disappear. The current and new plans both show 187 staterooms from 5001 through 5191. The changes are all category changes, not stateroom additions.
Deck 6 – Upper Verandah Deck Stateroom Changes
Current plan: Staterooms 6001-6177 | New plan: Staterooms 6001-6177
Deck 6 does not gain any new stateroom numbers, and it does not appear to lose any either. The current plan and the post-Project Evolution plan both run from stateroom 6001 through 6177, with the same total room count.
But this is definitely not a “nothing to see here” deck. Deck 6 gets a pretty significant category reshuffle, especially with the suites. The old SB, SC, and SS suite categories are being replaced by Holland America’s newer NS, NB, NC, GA, and GB categories. The verandah cabins also get cleaned up, with many VD cabins becoming VE and several VB cabins becoming VC or VS.
Deck 6 Count Summary
| Version | Room Range Shown | Total Staterooms |
|---|---|---|
| Current Deck Plan | 6001-6177 | 172 |
| Post-Project Evolution Deck Plan | 6001-6177 | 172 |
| Net Change | No staterooms added or removed | 0 |
What Was Removed To Make Room?
Nothing appears to have been removed on Deck 6 to make room for additional rooms. Unlike Deck 1, where new cabins appear to replace current public-service space, Deck 6 keeps the same stateroom footprint. The story here is category reshuffling, not new construction or removed cabins.
Current Deck 6 Categories

| IB | Interior | 5 |
| ID | Interior | 19 |
| IE | Interior | 9 |
What Actually Changed?
Deck 6 is all about reclassification. The room count stays exactly the same, but the category structure changes quite a bit. The biggest change is in the suite inventory. The current SB and SC Neptune Suites are split into NS, NB, and NC categories on the new plan, while the current SS Signature Suites become mostly GA, with four of them becoming GB.
The long run of current SS Signature Suites from the 6050s through the 6110s is mostly moving into the new GA category. Four of those suites, 6106, 6108, 6115, and 6117, become GB. The current SB suites at 6166 and 6177 become NS, while the other SB suites split into NB and NC. The current SC suites at 6164 and 6175 become NC.
The verandah categories also get cleaned up. The current VD cabins become VE. The current VC cabins stay VC. Several current VB cabins become VC, while two aft-side VB cabins, 6162 and 6173, become VS. The current VA cabins stay VA.
One of the more interesting changes is right up front. The current F ocean-view staterooms 6001 and 6002 become VC on the new plan. Since VC is shown under the verandah stateroom section on the new plan, this is one of those changes worth watching when Holland America eventually releases more detail.
The interior cabins also move into the newer naming system. The current I cabins become IB, while the current K and L cabins split between ID and IE. Again, same rooms, same deck, but a much different category map.

Rooms Added Or Removed On Deck 6
No new room numbers appear on Deck 6, and no existing room numbers disappear. The current and new plans both show 172 staterooms from 6001 through 6177. The changes are all category changes, not stateroom additions.
Deck 7 – Rotterdam Deck Stateroom Changes
Current plan: Staterooms 7000-7151 | New plan: Staterooms 7001-7151
Deck 7 is where things get interesting. This is not just a clean category conversion like we saw on some of the lower accommodation decks. Holland America appears to be doing some real surgery here, especially forward and aft.
The current Deck 7 plan shows a pair of Pinnacle Suites forward, staterooms PS7045 and PS7046. On the new plan, those forward Pinnacle Suites are gone from that location and that space is broken into smaller staterooms, including two new Vista Suites, TA7055 and TA7056, four VA verandah staterooms, and additional Neptune Suite inventory farther aft. Meanwhile, the aft end of the deck is completely reworked, with a new Pinnacle Suite, new Vista Suites, and a new Neptune Suite appearing where the current plan has aft-facing verandah and suite inventory.
Deck 7 Count Summary
| Version | Room Range Shown | Total Staterooms Counted |
|---|---|---|
| Current Deck Plan | 7000-7151 | 153 |
| Post-Project Evolution Deck Plan | 7001-7165 | 158 |
| Net Change | +5 |
What Was Removed To Make Room?
The biggest removal on Deck 7 appears to be the two forward Pinnacle Suites, PS7045 and PS7046. Those massive forward suites are no longer shown in that location on the new plan. Instead, that forward shoulder area of the ship is divided into smaller staterooms.
The old forward D-category cabins numbered around 7000 also disappear from the new plan. In their place, the forward-most section now starts with verandah staterooms, including VC7005 and VC7006, and VE staterooms beginning with 7001 through 7004.
Aft, the current plan’s combination of SB corner suites and aft-facing VB verandah cabins is replaced by a very different mix: a new aft Pinnacle Suite, several VS Vista Suites, a new NS Neptune Suite, additional VE verandah cabins, and new interior rooms. So Deck 7 is not just being recoded. It is being rebalanced.

What Actually Changed?
Forward, the current plan has a cluster of D-category ocean-view cabins around the very front of Deck 7, followed by VE and VD verandah cabins. On the new plan, those D-category rooms disappear, and the forward section becomes a mix of VE, VC, and IE staterooms. The old forward interiors also move into the new IE category.
The biggest forward change is the removal of the two forward Pinnacle Suites, PS7045 and PS7046. Those are replaced by smaller staterooms, including new Vista Suites TA7055 and TA7056, VA7057 through VA7060, and Neptune Suites beginning just aft of that area.
Midship, the current long run of SA Neptune Suites becomes mostly NA on the new plan, with some rooms becoming NB. The current I-category interior rooms 7049, 7051, and 7055 become IC7063, IC7065, and IC7069 on the new plan, which means the interior numbering and placement in that central section is also changing.
Aft, the current SB corner suites and aft-facing VB verandah cabins are replaced by a very different layout. The new plan shows a large aft Pinnacle Suite, PS7152, plus VS Vista Suites 7150, 7159, 7161, and 7163, and NS7165 in the starboard aft corner. That is a major repositioning of the aft suite inventory.
This is one of the decks where the drydock changes look genuinely structural. Deck 7 is not just “SA becomes NA” or “VE becomes VE.” Holland America appears to be moving the top suite real estate around, taking the Pinnacle Suite concept from the forward corners and shifting the big statement suite to the aft end of the ship.
Major Existing Stateroom Category Conversions
| Current Category / Area | New Category / Area | What Changes |
|---|---|---|
| Forward D-category rooms around 7000 | Removed/replaced by VE and VC numbering | Forward cabin layout changes |
| PS7045 and PS7046 | TA7055, TA7056, VA rooms, and nearby Neptune inventory | Forward Pinnacle Suites removed from this location |
| SA Neptune Suites | Mostly NA, with some NB | Suite category cleanup |
| SC Neptune Suites | NB | Reclassified suite inventory |
| Aft SB suites and VB aft-facing cabins | PS7152, VS7150, VS7159, VS7161, VS7163, NS7165, plus new VE and ID rooms | Aft section substantially reworked |
| Current L and M interiors aft | ID and IE interiors | Interior category and numbering changes |
Rooms Added Or Removed On Deck 7
Deck 7 appears to gain a net of five staterooms based on the room labels shown on the deck image. The old plan shows 153 rooms, while the new plan shows 158 rooms.
Notable rooms removed or no longer shown in the same form: the forward D7000-series rooms, PS7045, PS7046, and the current aft SB/VB layout.
Notable new aft rooms shown: PS7152, VE7153, ID7155, VE7157, VS7159, VS7161, VS7163, and NS7165.
Deck 8 – Navigation Deck Stateroom Changes
Current plan: Staterooms 8001-8147 | New plan: Staterooms 8001-8147
Deck 8 is one of the bigger stateroom stories in Oosterdam’s Project Evolution plans.
This is not just a category-code cleanup. Deck 8 gets a major overhaul. A large block of current Signature Suites are being replaced with smaller verandah staterooms. The aft Neptune Suites are no longer shown as suites in their current location. Former interior and verandah areas are reworked into a mix of standard verandahs, the new solo verandahs, interiors, and Vista Suites. In other words, Holland America is not just changing the letters on the doors here. A lot of the stateroom mix on this deck is changing.
Deck 8 Count Summary
| Version | Room Range Shown | Total Staterooms Counted |
|---|---|---|
| Current Deck Plan | 8001-8147 | 143 |
| Post-Project Evolution Deck Plan | 8001-8177 | 174 |
| Net Change | A lot of stateroom rework | +31 |
What Was Removed Or Reworked To Make Room?
The biggest change is that Deck 8 loses a large amount of existing suite-category space. On the current plan, Deck 8 has 50 SY Signature Suites, 2 SZ Signature Suites, and 2 aft SB Neptune Suites. On the new plan, that drops to just 2 Signature Suites in the original midship area, GC8080 and GB8082.
The old midship Signature Suite block is also dramatically changed. Most of those SY and SZ suites are now shown as VB verandah staterooms.
Aft, the former mix of VE, VF, VC, MM interiors, and the two SB suites gets reworked into a much denser stateroom section. The new plan adds standard VF verandahs, ID interiors, two VS rooms, four TS Vista Suites, and the two new aft NS Neptune Suites. This is where Deck 8 picks up most of its additional room count.

What Actually Changed?
Forward, the first block of rooms is fairly straightforward. The old VF cabins at the very front become VE, and the old forward VE cabins become VD. The six forward MM interiors become IE. So far, this looks like a category reshuffle.
Then the deck gets much more interesting. The current VA rooms around 8031 through 8036 become VB, and the large midship Signature Suite area begins to change almost immediately after that. Current SY rooms are mostly no longer suites. Many become VB verandah staterooms. Only two rooms in that old Signature Suite zone remain suite-category rooms: GC8080 and GB8082.
This is one of the biggest category drops on the ship so far. The current plan has 52 Signature Suites on Deck 8 when you combine SY and SZ. The new plan shows only 2 Signature Suites on this deck. Most of that old suite inventory becomes standard verandah inventory, which is a major change for anyone used to Deck 8 being a strong Signature Suite deck.
Moving aft, Holland America also introduces a large solo verandah section. A number of rooms that were previously part of the VE, VF, and MM interior mix are now shown as V1 and V2 solo verandahs. That is a meaningful product change because these are not just regular balcony cabins with new letters. They are being carved into a solo-category section, which changes how this part of Deck 8 will be sold.
This is a major rebuild, and it turns Deck 8 from a deck with a large suite block into a deck with a much denser mix of verandahs, solo verandahs, interiors, and a smaller number of suites.

Rooms Added Or Removed On Deck 8
No current Deck 8 room number completely disappears from the new plan, but several room numbers are reused in very different ways. That is important because this is not a clean one-to-one category change. Some former interior room numbers are now attached to verandah categories, former suite numbers become verandahs, and the new aft section adds a large group of additional staterooms.
Net result: Deck 8 appears to grow from 143 staterooms to 174 staterooms, a gain of 31, while also changing the character of the deck from suite-heavy to a much denser mix of verandahs, solo verandahs, interiors, and a smaller number of suites aft.
Deck 9 – Lido Deck Stateroom Changes
Current plan: No passenger staterooms | New plan: Staterooms 9001-9021
Deck 9 is another big one, and this time the changes are right up front. On the current Oosterdam plan, the forward section of the Lido Deck is public space. That is where the Fitness Center, Spa & Salon, and Hydro Pool are shown. On the post-Project Evolution plan, that forward area now becomes passenger stateroom space.
This is not a category reshuffle because there were no passenger cabins on Deck 9 before. Holland America is adding an entirely new block of staterooms to the Lido Deck, including two large Bridgeview Suites, a small group of verandah staterooms across the front, one interior room tucked behind them, and a run of verandah cabins along the starboard side.
Deck 9 Count Summary
| Version | Room Range Shown | Total Staterooms Counted |
|---|---|---|
| Current Deck Plan | No staterooms shown | 0 |
| Post-Project Evolution Deck Plan | 9001-9021 | 15 |
| Net Change | New forward Lido Deck stateroom section added | +15 |
What Was Removed Or Reworked To Make Room?
This one is pretty clear. The current Deck 9 plan shows the Fitness Center and Spa & Salon at the very front of the ship, with the Hydro Pool just aft of that area. On the new plan, that forward section is where the new stateroom block appears.
That does not automatically mean those venues are gone from the ship entirely. Holland America has only released this stateroom-focused version of the future plan, so we do not yet know where the fitness center, spa facilities, or other related spaces are being moved, resized, or replaced. But they are no longer shown in that forward Deck 9 location on the new plan.
The Lido Pool remains shown farther aft on Deck 9, and the Sea View Pool is still shown at the back of the deck. The major forward change is the conversion of the old fitness, spa, and hydro-pool zone into new passenger accommodations. You can also notice some physical changes to the layout of the of the Lido Market, both the Lido and Sea View Pools and other spaces on this deck.

What Actually Changed?
Forward, Holland America is creating something completely new for Oosterdam: two Bridgeview Suites on Deck 9. These are labeled PH9005 and PH9006 on the new plan. The description on the plan calls them Bridgeview Suites with panoramic windows and a wraparound balcony, which makes sense given their location right at the forward top of the ship.
Just in front of and beside those suites, the new plan also shows four small forward verandah rooms: VC9001, VC9002, VE9003, and VE9004. These sit in the same general forward zone where the current plan shows spa and fitness space, so this is not a simple renaming exercise. This is new passenger accommodation where public wellness space used to be shown.
There is also one interior room, IE9008, tucked just behind the new forward suite and verandah layout. It is a small addition compared to the Bridgeview Suites, but it matters because it shows Holland America is using this area very efficiently. When they decided to turn this part of the ship into cabins, they really used the space.
Along the starboard side, the new plan adds a run of eight VC verandah staterooms: VC9007, VC9009, VC9011, VC9013, VC9015, VC9017, VC9019, and VC9021. That gives Deck 9 a brand-new stateroom presence where it previously had none, and it makes the Lido Deck a very different animal after the drydock.
New Rooms Added On Deck 9
| New Category | Room Numbers | Count |
|---|---|---|
| PH Bridgeview Suites | 9005, 9006 | 2 |
| VC Verandah | 9001, 9002, 9007, 9009, 9011, 9013, 9015, 9017, 9019, 9021 | 10 |
| VE Verandah | 9003, 9004 | 2 |
| IE Interior | 9008 | 1 |
Rooms Added Or Removed On Deck 9
Deck 9 currently has no passenger staterooms, so nothing is being removed from the stateroom inventory here. Instead, Holland America is adding 15 new staterooms in the forward section of the Lido Deck.
New staterooms added: PH9005, PH9006, VC9001, VC9002, VE9003, VE9004, IE9008, VC9007, VC9009, VC9011, VC9013, VC9015, VC9017, VC9019, and VC9021.
Net result: Deck 9 goes from zero passenger staterooms to 15, while the forward fitness, spa, and hydro-pool area shown on the current plan is replaced by new passenger accommodations on the future plan.
Deck 10 – Observation Deck Stateroom Changes
Current plan: Staterooms 10001-10026 | New plan: Staterooms 10001-10018
Deck 10 is a much smaller stateroom section, but it still gets a meaningful change. This is not a deck where Holland America is adding rooms. It is actually going in the other direction. The current Observation Deck plan shows a small group of verandah staterooms along both sides, plus a block of interior staterooms tucked behind the elevators. On the new plan, that interior block is gone.
The side verandah cabins remain, but they are not just a clean one-for-one carryover. The forward group changes from VB to VC, the aft side cabins stay in the VB family, and several room numbers that used to belong to the interior cabins are now used for verandah cabins. So Deck 10 ends up with fewer total rooms, no interior staterooms, and a cleaner verandah-only layout.
Deck 10 Count Summary
| Version | Room Range Shown | Total Staterooms Counted |
|---|---|---|
| Current Deck Plan | 10001-10026 | 25 |
| Post-Project Evolution Deck Plan | 10001-10018 | 18 |
| Net Change | Interior cabin block removed | -7 |
What Was Removed Or Reworked?
The main thing removed on Deck 10 is the current interior stateroom block behind the elevators. The old plan shows seven K-category interior rooms in this section: K10012, K10013, K10016, K10017, K10020, K10021, and K10024. On the new plan, there are no interior staterooms shown on Deck 10 at all.
The outboard verandah cabins are also reworked. The current plan has all 18 side cabins listed as VB. On the new plan, the first four cabins on each side become VC, while the remaining five on each side are VB. That gives the new Deck 10 a split between 8 VC verandahs and 10 VB verandahs.
There is also some room-number cleanup happening here. The current plan uses higher numbers like VB10019, VB10022, VB10023, and VB10026 at the aft end of the stateroom block. The new plan stops at 10018, and some numbers that used to be assigned to interior rooms, such as 10012, 10013, 10016, and 10017, are now used for verandah cabins. Same general stateroom zone, but a very different layout.
Current Deck 10 Categories
| Current Category | Type | Current Count |
|---|---|---|
| VB | Verandah | 18 |
| K | Interior | 7 |
New Deck 10 Categories
| New Category | Type Shown On Plan | New Count |
|---|---|---|
| VC | Verandah | 8 |
| VB | Verandah | 10 |
What Actually Changed?
The side cabins remain, but the category mix changes. Current VB10001 through VB10008 become VC10001 through VC10008. The next run of verandahs becomes VB10009 through VB10018. That gives Deck 10 a cleaner and shorter stateroom range.
The bigger change is inside. The current K-category interior rooms behind the elevator bank are removed from the new Deck 10 plan. This is the opposite of what happens on some of the other decks, where Holland America is squeezing in more rooms. Here, the deck actually loses staterooms.
The end result is a simpler Deck 10 accommodation layout: verandah rooms only, no interiors, and a smaller total cabin count. It is not the headline-grabbing change that Deck 8 or Deck 9 gets, but for anyone who likes those tucked-away Observation Deck interiors, those appear to be gone after the drydock.
Existing Stateroom Category Conversions
| Current Category / Area | New Category / Area | What Changes |
|---|---|---|
| VB10001-VB10008 | VC10001-VC10008 | Forward verandahs recategorized |
| Middle/aft VB staterooms | VB10009-VB10018 | Verandah numbering tightened |
| K interior block | Removed from new Deck 10 stateroom plan | Deck loses interior cabins |
Rooms Added Or Removed On Deck 10
Deck 10 does not gain any staterooms. Instead, it loses the current interior cabin block and ends up with 18 verandah staterooms.
Interior rooms removed from the new plan: K10012, K10013, K10016, K10017, K10020, K10021, and K10024.
New category layout: VC10001, VC10002, VC10003, VC10004, VC10005, VC10006, VC10007, VC10008, VB10009, VB10010, VB10011, VB10012, VB10013, VB10014, VB10015, VB10016, VB10017, and VB10018.
Net result: Deck 10 drops from 25 staterooms to 18, with the interior rooms removed and the remaining side cabins organized into VC and VB verandah categories.
Deck 11 – Sports Deck Stateroom Changes
Current plan: No passenger staterooms | New plan: Staterooms 11001-11016
Deck 11 is another deck where Holland America is adding passenger accommodations where there were none before. The current Sports Deck is shown as public space, but on the new post-Project Evolution stateroom plan, this deck gets a new block of cabins.
Unlike Deck 9, where the new rooms are a mix of standard verandahs and Bridgeview Suites, Deck 11 gets a more premium-leaning mix. The new plan shows six solo verandah staterooms, two TC Vista Suites, and eight TA Vista Suites. So this is not just “let’s squeeze in a few rooms.” Holland America is turning the forward Sports Deck into a new accommodation area with a lot of suite-category inventory.
Deck 11 Count Summary
| Version | Room Range Shown | Total Staterooms Counted |
|---|---|---|
| Current Deck Plan | No staterooms shown | 0 |
| Post-Project Evolution Deck Plan | 11001-11016 | 16 |
| Net Change | New Sports Deck stateroom section added | +16 |
What Was Removed Or Reworked To Make Room?
The current Deck 11 plan does not show any passenger staterooms. Instead, it shows public and activity spaces. The new plan replaces the forward portion of this deck with new passenger accommodations.
Since Holland America has only released the future stateroom version of the deck plans, this does not tell us the full story of what’s happening with the Sports Deck, whether it’s being resized, or whether it’s removed entirely. What the new plan does show clearly is that the Sports Deck gains a brand-new stateroom section where none existed before.
The addition is not small either. Deck 11 picks up 16 new rooms, including eight TA Vista Suites and two TC Vista Suites. That is a pretty notable change for a deck that previously did not have passenger cabins at all.
Current Deck 11 Categories
| Current Category | Type | Current Count |
|---|---|---|
| None | No passenger staterooms currently shown on Deck 11 | 0 |
New Deck 11 Categories
| New Category | Type Shown On Plan | New Count |
|---|---|---|
| TA | Vista Suite | 8 |
| TC | Vista Suite | 2 |
| V1 | Solo Verandah | 6 |
What Actually Changed?
The forward part of Deck 11 changes from public/activity space into a new stateroom zone. That is the main story here. Unlike Deck 10, where the ship actually loses interior rooms, Deck 11 is pure addition from a stateroom perspective.
The most interesting rooms are TA11001 and TA11002, which sit at the forward corners of the new layout. TA11001 is also specifically listed in Holland America’s accessibility notes as a fully accessible suite with a roll-in shower only, so this is not just a random new room number added to the deck plan.
Behind those forward TA suites, the new plan shows a symmetrical run of Vista Suites on both sides: TC11009 and TC11010, plus TA11011, TA11012, TA11013, TA11014, TA11015, and TA11016. That gives the Sports Deck a real suite presence where there was previously no passenger cabin inventory at all.
The smaller new addition is the solo verandah group. The plan shows six V1 solo verandahs, V1-11003 through V1-11008. Between the solo verandahs and the new Vista Suites, Deck 11 becomes one more example of Holland America using this drydock to create new sellable cabin inventory in spaces that were not passenger staterooms before.
New Rooms Added On Deck 11
| New Category | Room Numbers | Count |
|---|---|---|
| TA Vista Suites | 11001, 11002, 11011, 11012, 11013, 11014, 11015, 11016 | 8 |
| TC Vista Suites | 11009, 11010 | 2 |
| V1 Solo Verandahs | 11003, 11004, 11005, 11006, 11007, 11008 | 6 |
Rooms Added Or Removed On Deck 11
Deck 11 currently has no passenger staterooms, so no existing cabins are removed or recategorized. The change is entirely new stateroom inventory.
New staterooms added: TA11001, TA11002, V1-11003, V1-11004, V1-11005, V1-11006, V1-11007, V1-11008, TC11009, TC11010, TA11011, TA11012, TA11013, TA11014, TA11015, and TA11016.
Net result: Deck 11 goes from zero passenger staterooms to 16, with the new cabin mix heavily weighted toward Vista Suites plus a small run of solo verandahs.
