There’s something deliciously eerie about being at sea in October. The ocean seems darker, the nights stretch a little longer, and when the moonlight hits the waves just right, you could almost swear you see something watching from the mist. Onboard, pumpkins glow in the atrium, cobwebs hang from railings, and laughter from the costume party drifts down the corridors.
If you’re lucky enough to spend Halloween on a cruise, you’re in for more than just tropical sunsets and midnight buffets – you’re stepping into a floating haunted playground where the drinks are bubbling, the costumes are wild, and the parties last long past the witching hour. Some cruise lines go all in with massive deck parties and costume parades, while others keep it classy with eerie elegance and spooky cocktails. Either way, a Halloween cruise is equal parts fright and delight.
Here’s what you can expect if you’re sailing with Carnival, Royal Caribbean, Disney, MSC, Princess, Norwegian, Virgin Voyages, Margaritaville at Sea, or Holland America this Halloween season.
Carnival Cruise Line
Nobody does fun quite like Carnival, and Halloween is no exception. Every ship in the fleet gets decked out for the season, complete with cobwebs, pumpkins, and crew members who are just as excited to celebrate as the guests. Carnival’s Frightfully Fun cruises run throughout October, so even if your sailing doesn’t fall directly on Halloween, you’ll still get the full spooky treatment. Expect costume contests for both adults and kids, dance parties that turn into full-blown monster mashes, and even trick-or-treating around the ship.
Carnival also rolls out a few Halloween-themed menu items, specialty cocktails, and festive desserts, while Dive-In Movies might feature something like Hocus Pocus or The Nightmare Before Christmas under the stars. The line encourages guests to bring costumes, door decorations, and Halloween-themed accessories, but make sure to follow the rules – no masks or fake weapons allowed. It’s all in good fun, and it’s one of the best times of year to be onboard a Carnival ship if you love themed cruising.

Disney Cruise Line
Disney practically invented holiday magic, and Halloween on the High Seas is a perfect example of that. Every fall, Disney’s ships transform into floating haunted mansions, complete with a giant Pumpkin Tree that “comes to life,” characters dressed in Halloween costumes, and a lineup of spooky-but-not-too-scary fun that appeals to both kids and adults.
Guests can look forward to trick-or-treating, themed deck parties, Halloween movie nights, and even villain takeovers where some of Disney’s famous baddies come out to play. Themed snacks and desserts pop up throughout the ship, and you’ll find plenty of photo ops with Mickey, Minnie, Goofy, and the gang in costume. Disney keeps the experience lighthearted and family-friendly – no haunted houses or jump scares here – but the attention to detail and atmosphere make it one of the most memorable holiday sailings on the seas.

Royal Caribbean
Royal Caribbean has been expanding its Halloween celebrations across the fleet, and now most ships get in on the spooky action all October long. Expect to see themed decorations around the Royal Promenade, costume contests, and family trick-or-treating hosted by Adventure Ocean staff. Some ships even go all out with haunted houses, fog machines, and crew costume parades that rival anything you’d see on land.
Royal’s Halloween deck parties are big, energetic events that pull together cruisers of all ages, complete with DJs, dancing, and drink specials. Families will find plenty of kid-friendly activities during the day, while adults can look forward to costume-themed nightlife once the sun goes down. Depending on the ship, programming may vary – some are known for going all in, while others keep things simpler. Either way, you’ll get a fun and festive experience with Royal Caribbean’s signature high-energy twist.
MSC Cruises
MSC tends to add a European flair to its Halloween festivities. On U.S.-based ships like MSC Seascape or MSC World America, you can expect costume parades, themed parties, and Halloween-inspired menus in the buffet and lounges. Decorations are typically concentrated in public areas – think pumpkins, spider webs, and moody lighting – while crew members often join in the fun with costumes of their own.
You’ll also find spooky movie screenings, themed trivia, and family-friendly haunted events in the kids’ clubs. While MSC’s celebrations can sometimes feel more understated than the American lines, they’re still a fun way to get in the Halloween spirit, especially if you’re sailing in late October. Onboard atmosphere can vary depending on the ship and itinerary, but you can safely pack a costume and expect at least a few eerie touches.
Princess Cruises
Princess Cruises tends to approach Halloween with a bit more sophistication, blending its signature elegance with a festive twist. Picture pumpkins and cobwebs adorning the Piazza, passengers dressed to impress in creative costumes, and bartenders shaking up themed cocktails with names like “Devil’s Brew” or “Zombie Smash.”
Onboard entertainment often includes scary movie nights, themed trivia, and special Halloween-themed activities for kids and adults alike. The highlight is usually a grand costume parade and contest, where guests can show off their creativity for prizes and bragging rights. Princess keeps things classy but festive – perfect if you want to celebrate without going full haunted house.
Norwegian Cruise Line
Norwegian Cruise Line knows how to throw a party, and their Halloween sailings are no exception. Expect lively costume contests, ship-wide Halloween bashes, and plenty of themed fun woven into the daily schedule. From spooky scavenger hunts and horror movie screenings to Halloween trivia and dance parties, there’s something for everyone.
The vibe is more “fun and festive” than “fright and frightful,” though some crew and guests really lean into creative and sometimes over-the-top costumes. NCL’s entertainment teams are known for getting guests involved, and you might even find themed game shows or murder mystery dinners depending on your ship. Whether you’re looking for a family-friendly celebration or an adults-only dance floor full of ghosts and pirates, Norwegian keeps the energy high and the atmosphere lighthearted.
Virgin Voyages
If you prefer your Halloween celebrations with a little more edge (and zero kids), Virgin Voyages has you covered. Their “Halloween Voyages: No Kids. Just Treats.” are adults-only sailings that mix the usual Virgin flair with eerie, cheeky fun. Expect ship-wide costume contests, live entertainment that gets a spooky remix, and deck parties that last well into the night.
There are themed shows, creepy cocktails, and even activities like skull painting or haunted grog walks. Sailors are encouraged to go bold with their costumes – think glam, gothic, and outrageous rather than basic store-bought looks. Virgin’s ships already have a moody, modern vibe, so the Halloween overlay feels like a natural fit. It’s less “trick-or-treat” and more “let’s dance until sunrise with a coven of vampires.”

Margaritaville at Sea
If your kind of Halloween involves a margarita in one hand and a skeleton lei around your neck, Margaritaville at Sea’s Sail the Haunted Seas cruises are for you. The line has leaned into Halloween with a tropical-meets-spooky vibe that’s equal parts party and parody. Bars and lounges are re-themed with eerie twists, there’s a “White Hot Neon Nightmares” glow party, and passengers are encouraged to dress up for costume contests and onboard events.
Expect fun cocktails with names like “Potent Potions,” Halloween trivia, and a healthy dose of mischief from the cruise staff. It’s the perfect option for anyone who wants Halloween fun without taking it too seriously – think Halloweentown meets Margaritaville.
Holland America Line
Holland America brings a touch of classic style to Halloween at sea, proving that you don’t have to trade elegance for a little spooky fun. The line’s celebration includes pumpkin carving contests, costume parades, themed trivia, and festive treats in the Lido Marketplace. Ships get subtle seasonal décor, and you’ll often find themed cocktails or desserts served in the bars and dining rooms.
The highlight for many guests is the evening costume party, which tends to be a more laid-back affair than the all-night bashes you’ll find on other lines – but it’s just as enjoyable. Holland America’s version of Halloween strikes a balance between playful and polished, making it ideal for travelers who like a little seasonal spirit without an over-the-top production.

Tips Before You Board
A little prep makes Halloween at sea even better. Use this quick checklist to dial in the fun.
- Pack at least one costume and a simple backup piece like a tee or headband.
- Review your line’s costume rules. Skip masks, face paint that hides identity, and any prop weapons.

- Expect differences ship to ship. Scan the daily program when you board.
- Bring a few magnetic door decorations and a small tote for candy.
- Budget for themed drinks and photos. These are often extra.

Whether you’re chasing candy with your kids, dancing under the stars in costume, or sipping a “Witch’s Brew” on deck, one thing’s for sure – celebrating Halloween at sea is a treat you won’t forget.
