Royal Caribbean Oasis Class vs Icon Class: Which Should You Book?

So you’ve decided you want to sail one of Royal Caribbean’s giant ships. Good news, you’ve basically got two options: an Oasis class ship or an Icon class ship. Bad news, they look a lot alike in the brochure, they sail a lot of the same Caribbean routes, and they both stop at Perfect Day at CocoCay. So how do you pick?

I’ll be upfront with you about where I’m coming from. I’ve sailed Oasis class, and I’ve also sailed MSC’s World class, which is pretty much MSC’s take on the Oasis class. I can deal with those big ships. But Icon? I don’t think I can ever bring myself to book one. The over the top everything and the sheer number of families with kids onboard is a deal breaker for me. That said, I’m not everybody, and for a lot of you Icon might be exactly the right call. So let’s walk through it together and you can decide for yourself.

First, the Quick Numbers

Here’s the thing that surprises most people. These ships aren’t that different in size. Icon is only about 5 to 6 percent bigger than Wonder and Utopia, the largest Oasis class ships. What’s different is how Royal Caribbean decided to fill all that space.

Take a look at that max guest number for a second. 7,600 people. That’s every bunk, pull down and sofa bed filled, which is exactly what happens on a ship designed around families, especially during school breaks. To be fair, Icon’s double occupancy count is actually a hair lower than Wonder’s. Whether you feel it at the line for the waterslides in July is another story.

The Oasis Class Lineup

Oasis of the Seas showed up in 2009 and honestly changed the game. Neighborhoods, a real park with living trees in the middle of a ship, the Boardwalk with its carousel and outdoor AquaTheater. All of it started here. And Royal Caribbean has kept the older ships from feeling tired with their big “Royal Amplified” makeovers, so don’t write off a 2010 ship just because of the date.

The Icon Class Lineup

Icon of the Seas launched in January 2024 as the world’s largest cruise ship, and its sisters all share that crown since they’re built to the same 248,663 ton footprint. Royal Caribbean likes to point out that each one isn’t a carbon copy, and that’s fair. Every ship gets its own Broadway show, its own supper club and a few toys the others don’t have. Because apparently one record breaking waterpark per class wasn’t enough.

Nine pools on Hero, by the way. Nine. I’m not sure who asked for that, but somebody at Royal Caribbean clearly thought seven was holding them back. Legend’s worth calling out for a different reason, since it’s the first Icon ship to sail Europe.

What They’ve Got in Common

Before I start picking on Icon, let’s be fair about how much carries over. If you’ve sailed Oasis class, a good chunk of Icon is going to feel familiar.

• Central Park. Both classes have the open air park in the middle of the ship, lined with specialty restaurants and bars.
• Royal Promenade. The indoor main street with shops, bars and parades is on both. Icon’s version has more windows and The Pearl sculpture at one end.
• AquaTheater shows. Oasis class runs them outdoors at the back of the Boardwalk. Icon moved the AquaTheater indoors under the glass AquaDome.
• Ice shows, FlowRider and mini golf. You’ll find all three on both.
• Broadway style productions. Full length musicals in the main theater on both classes.
• Familiar dining and bars. Chops Grille, Izumi, Playmakers and the Schooner Bar all show up on both.
• Adventure Ocean. The kids club and teen spaces are on both, so yes, Oasis class has plenty of kids too. Just not in the same concentration.
• Suite tiers and Royal Genie service. Both use the Sea, Sky and Star class suite setup, with the top suites getting a Royal Genie.
• Perfect Day at CocoCay. Pretty much every Caribbean itinerary on both classes stops there.

Neighborhood by Neighborhood

Here’s where things begin to change between the two classes. Royal Caribbean kept the two neighborhoods everybody loves and then rebuilt almost everything else for Icon.

Surfside is the one that tells you everything about who Icon’s built for. On Oasis class, the Boardwalk is a fun open air hangout for everybody. On Icon, that same real estate at the back of the ship became a neighborhood designed around young families, with Splashaway Bay, Baby Bay, a carousel and the Water’s Edge pool so mom and dad can sit while the kids splash.

Adults do get a consolation prize in The Hideaway, an adults only beach club with the first suspended infinity pool at sea. I’ll admit it looks great. I’ll also admit I’m skeptical that one adults only deck balances out a ship that’s this all in on families.

Stuff You’ll Only Find on One or the Other

I’ll give Icon credit on the pools. On Oasis class, the main pool deck is one big crowded space on a single deck, and on a sea day you’d better have a plan for finding a lounger because the chair hogs get up early to start claiming spots! Icon spreads seven pools across five decks, with four in Chill Island alone.  And Crown’s Edge, where you literally dangle off the side of the ship on a ropes course? Fun to watch. Hard pass for me, though.

Cabins and Suites

Both classes run the full range from inside cabins to multi level lofts, but Icon added a pile of new categories, and you can probably guess who most of them are aimed at.

Quick word on Infinite Balconies, because people get surprised by these. There’s no separate outdoor deck. The glass wall drops down and the “balcony” becomes part of the room. Some folks love the extra indoor space. Others want a real balcony where they can close the door behind them and sit outside in peace. And a Surfside view balcony? You’re paying extra to overlook a splash pad.

Let’s Talk Money

This is where a lot of you are going to make your decision, and honestly, it’s where I’d make mine even if the kids weren’t a factor. Icon class fares have run way ahead of Oasis class since day one. For example, balcony cabins on January 2026 Icon sailings started around $2,426 per person, while similar Harmony balconies that same month started around $949. Prices move constantly, but paying double or more for Icon isn’t unusual at all.

Think about what that extra money actually buys you. Same Central Park. Same Promenade. Same Chops. Same ice show. Basically you’re paying for the waterpark, the pools and Surfside. If you’ve got kids, that might be worth every penny. If you don’t, that’s a lot of cash for stuff you’ll mostly be avoiding.

Oasis class also gives you more flexibility. Utopia, Wonder and Oasis are all running three and four night getaways, so you can try a mega ship over a long weekend without committing a whole week. Icon mostly sticks to seven nights.

So Which One Should You Book?

If you’ve got young kids, book Icon and don’t look back. It’s the best family ship Royal Caribbean’s ever built, and you’ll probably have a fantastic week. I mean that.

But if you’re a couple, an adult group, or just someone who’s been cruising long enough to know what you actually like, Oasis class gets you most of the experience for a lot less money and a lot fewer pool noodles to the face. That’s where I’ve landed. I’ve enjoyed my time on Oasis class, and I liked MSC’s World class for a lot of the same reasons. Icon just takes everything a few steps too far for my taste, and paying a premium to share a ship with that many families during their big vacation isn’t my idea of a relaxing week at sea.

Still on the fence? Price out the same week on both and ask yourself one question. Is the difference worth Category 6 and Surfside to you? If the answer’s yes, enjoy the waterpark. If it’s no, welcome to the Oasis class club. We’ve got the zip line.
