☀️ 25 Things to Do on a Sea Day: Fun, Sun & Everything in Between
Updated: Aug 16
One of the best parts of cruising is the sea days. No rushing to catch an excursion. No alarm clock. No racing back to the ship before all aboard. Just an entire day to relax, explore, and enjoy everything your cruise ship has to offer.
Whether you're the type who spends all day by the pool or loves packing your schedule with activities, sea days are your chance to cruise exactly the way you want.
Depending on your ship, that could mean waterslides and trivia, a leisurely brunch, live music, a spa day, a show, or finding a quiet spot where you can sit and watch nothing but ocean for miles.
Here are 25 of my favorite ways to make the most of a cruise sea day.
Good to know: Activities vary by cruise line, ship, and sailing, so check your cruise line's app or daily schedule once you're onboard to see exactly what's happening during your sea day.
1. Start the Morning Slow
Sea days were made for sleeping in. Skip the early wake-up call, order room service, sip coffee on your balcony, and enjoy watching nothing but the ocean for miles.
One of my favorite cruise hacks is packing a travel mug and a few coffee extras from home. It's an easy way to upgrade your morning coffee without spending extra onboard.
2. Don't Miss a Sea Day Brunch
Instead of grabbing a quick breakfast before rushing off the ship, sea day gives you time to actually sit down and enjoy the morning.
Some cruise lines offer special brunch or extended breakfast options on sea days. Carnival's SeaDay Brunch is one of our favorites, but what's available varies by cruise line and ship.
Check your cruise line's app or daily schedule to see what's available. You may find a sit-down breakfast or brunch you've been overlooking on busy port mornings.
3. Claim Your Spot by the Pool
Sea days are made for sunshine.
Grab a lounge chair, take a dip in the pool, relax in the hot tubs, or simply enjoy watching the ocean go by. Since everyone is onboard on a sea day, the pool deck can get busy, so heading out a little earlier can make finding a good spot easier.
Don't forget a few pool-day essentials:
Swimsuit
Cover-up
Sandals
Sunscreen
Towel bands or clips—they're lifesavers on windy days!
And remember to reapply that sunscreen. The ocean breeze can make it surprisingly easy to forget how much sun you're actually getting.

4. Relax in an Adults-Only Retreat
If the main pool deck gets a little too busy, see whether your ship has an adults-only retreat or quieter outdoor area.
Carnival has Serenity on many ships, Royal Caribbean has Solarium spaces on many of its ships, and other cruise lines have their own versions. These areas can be perfect when you want the sunshine and ocean views without quite as much activity around you.
Bring a book, grab a drink, find a chair, and enjoy having nowhere else you need to be.
5. Ride the Waterslides & Try the Ship's Big Attractions
Today's cruise ships can have some pretty incredible attractions. Depending on your ship, you might find waterslides, surf simulators, ropes courses, zip lines, go-kart tracks, rock-climbing walls, bumper cars, water coasters, or something completely different.
This is why it's worth researching your specific ship, not just your cruise line. Even two ships from the same company can offer completely different experiences.
Sea days give you plenty of time to finally try that attraction you've been eyeing since embarkation day.
6. Play Trivia
Trivia is one of those classic cruise activities that's easy to overlook until you try it. Topics can range from music and movies to general knowledge, sports, television, decades, and pop culture.
It's usually casual, doesn't take very long, and is easy to fit between pool time, lunch, or whatever else you're doing.
Just be warned: some cruisers take their trivia very seriously. 😂
7. Join a Game Show, Contest or Scavenger Hunt
Sea days are when cruise ships really come alive. Browse the daily schedule and you'll often find game shows, contests, scavenger hunts, karaoke, pool games, and all kinds of other activities happening around the ship.
Take a few minutes the night before or over morning coffee to look through the schedule and save anything that catches your attention. On Carnival, we use the HUB App, while other cruise lines have their own apps or daily schedules.
We don't try to plan every minute. Pick a few things that sound fun and leave room for whatever you discover along the way.
8. Take a Dance, Craft or Enrichment Class
Sea days are a great time to try something new.
Depending on your cruise line and sailing, you might find cooking demonstrations, dance classes, crafts, destination talks, educational presentations, art activities, or other enrichment programs.
Some cruise lines offer more of these activities than others, so check the schedule even if you don't normally think of yourself as someone who takes classes on vacation. You might find something you weren't expecting.
9. Explore the Ship From Top to Bottom
Sea days are the perfect excuse to explore every corner of the ship.
Walk decks you haven't visited yet. Find the lounges. Look at the artwork. Wander through the atrium. Find an outdoor deck or quiet seating area you didn't know existed.
This is especially worthwhile on larger ships. It's surprisingly easy to reach the end of a cruise and realize there were entire areas you never saw.
We've found some of our favorite little spots onboard simply because we started wandering with nowhere particular to go.
10. Skip the Buffet and Try Somewhere Different for Lunch
Here's one of my favorite cruise tips: don't automatically head to the buffet just because it's lunchtime.
Sea days are a great opportunity to try some of the other dining options around the ship. Depending on your cruise line and ship, you may have restaurants or casual venues that are included in your cruise fare at lunchtime.
Carnival is a great example. Depending on the ship, complimentary sea-day lunch options can include venues or lunch concepts associated with places such as Cucina del Capitano, JiJi Asian Kitchen, Chibang!, Guy's Pig & Anchor, and other ship-specific restaurants.
The exact restaurants and whether they're included can change from ship to ship, so always check what's available on your sailing.
Menus may be different from dinner service, but sea day is a fun opportunity to try something new without automatically joining the buffet crowd.
11. Listen to Live Music
You don't have to wait until nighttime for entertainment. Walk around the ship during a sea day and you may find musicians playing in the atrium, lounges, pool areas, or other venues.
Some of our favorite cruise moments are the ones we never planned. You might be heading somewhere else and end up stopping to listen to a guitarist, pianist, or band for half an hour.
Not every memorable cruise experience has to be on your schedule.
12. See a Show or Live Performance
Cruise ships can offer some impressive entertainment, so make time to see what's playing.
Depending on your cruise line and ship, you might find musical productions, comedy, guest entertainers, magic, ice shows, aquatic performances, or other live entertainment.
Some popular shows require reservations or fill up quickly, so check your cruise line's app to see how entertainment works on your particular ship.
13. Watch a Movie at Sea
There's something fun about watching a movie while you're sailing across the ocean.
Depending on the ship, you might find movies playing on a giant outdoor screen by the pool, in an indoor theater, or in another entertainment venue. An outdoor movie under the stars can be especially fun once the sun goes down.
Movies are also a great backup when the weather isn't cooperating or you simply want something relaxing to do.
14. Spend Some Time at the Spa or Thermal Suite
If relaxing is the goal, sea day is a perfect time to slow things down even more.
Cruise ship spas commonly offer massages, facials, salon treatments, and other services for an additional charge. Some ships also have thermal suites with heated loungers, steam rooms, saunas, hydrotherapy pools, or other relaxation areas.
Sea days can be popular spa days, so if there's a treatment or experience you really want, don't necessarily wait until the last minute to book it.
15. Play Mini Golf, Pickleball or Other Sports
If sitting still all day isn't your thing, see what recreational activities your ship has.
Depending on the ship, you might find mini golf, pickleball, basketball, table tennis, fitness classes, walking or jogging tracks, and other sports.
Even walking a few laps outside with nothing but ocean around you feels a little different from exercising at home.
16. Check Out the Arcade, Escape Room or Virtual-Reality Activities
Some ships have taken indoor entertainment way beyond traditional arcade games.
Depending on your ship, you might find an arcade, escape room, laser tag, virtual-reality experiences, interactive games, or other high-tech attractions. Some are included while others cost extra or require reservations.
This is another reason it's worth researching your specific ship before you sail. You may have something onboard you didn't even realize was there.
17. Pack a Few Travel Games
Travel-size games don't take up much room, but they're surprisingly fun onboard.
They're perfect for hanging out in a lounge, relaxing on your balcony, spending time with family, or even meeting new cruise friends. A simple deck of cards or magnetic travel game can provide hours of entertainment without requiring a schedule or reservation.
Some ships also have libraries or game areas with board games available to borrow.
18. Take Time to Unplug
Sea days are perfect for slowing down.
Read a book, listen to an audiobook, catch up on your favorite podcast, sit on your balcony, or simply enjoy the sound of the ocean.
Before your cruise, download anything you'll want while you're offline. Ship Wi-Fi packages and connectivity vary, and having your books, podcasts, music, or audiobooks downloaded ahead of time means you don't have to think about it once you're at sea.
Kindle Unlimited has become one of my favorite ways to stock up on vacation reading before a cruise.
19. Bar Hop Around the Ship
Sea days are the perfect excuse to explore some of the ship's different bars and lounges.
Try a different bar, order a new cocktail—or mocktail—and discover a few hidden favorites. Each venue can have its own atmosphere, menu, entertainment, or view, and you may be surprised which one becomes your go-to spot for the rest of the cruise.
You don't need to turn it into a marathon. Pick a couple of places you haven't tried, sit down, and enjoy them.
And don't forget the water!
20. Test Your Luck in the Casino
If you enjoy gambling, the casino is another option while the ship is at sea. Depending on the ship, you'll typically find slot machines and table games, and some sailings also schedule tournaments or other casino events.
Obviously, this is one activity that can cost money quickly. Decide what you're comfortable spending before you start and stick to it.
If gambling isn't your thing, skip it. That's the beauty of a sea day—there's always something else to do.
21. Play Bingo
Bingo is a classic cruise activity and can draw a surprisingly big crowd, especially when there's a larger prize involved.
It's also something different generations can easily do together, making it a fun option if you're traveling with family or a group.
Bingo generally costs extra, so check your daily schedule for times, packages, and pricing.
22. Take a Behind-the-Scenes Ship Tour
Have you ever wondered what happens behind all those doors passengers normally can't enter?
Some cruise lines and ships offer behind-the-scenes tours that give passengers a closer look at how the ship operates. Depending on the tour, you might see areas such as the galley, backstage spaces, laundry facilities, engine control room, or even the bridge.
These tours aren't available on every ship and may cost extra or have limited capacity. If your sailing offers one and you're interested, check into it early.
23. Enjoy Afternoon Tea or Another Cruise Tradition
Many cruisers don't even realize afternoon tea may be available on their ship.
Depending on the cruise line and sailing, afternoon tea may include tea alongside finger sandwiches, scones, pastries, or small desserts. It's quiet, relaxing, and a nice break from the busy pool deck.
Availability, timing, what's served, and whether it's complimentary vary by cruise line and ship, so check your daily schedule rather than assuming it will be offered.
And don't stop at afternoon tea. Different cruise lines have their own little traditions and sea-day experiences. Trying one is part of the fun of sailing with different lines.
24. Watch the Sunset From the Open Deck
With all the activities happening onboard, it's surprisingly easy to forget one of the best parts of cruising:
You're in the middle of the ocean.
Find an open deck, grab a comfortable spot, and watch the sun disappear over the horizon.
Take the picture first—I know you're going to. 😂 Then put the phone down for a few minutes and enjoy it.
Some of my favorite cruise memories aren't from an excursion or scheduled activity at all. They're moments like this.
25. End the Day in Style
Sea-day evenings are often some of the busiest—and most fun—nights of the cruise.
Depending on your cruise line and itinerary, you might find a formal or elegant night, production shows, comedy, theme parties, live music, deck parties, dancing, or other late-night entertainment.
I like to look at the evening schedule ahead of time so we know whether there's anything we don't want to miss. If it's a dressier night, choosing your outfit beforehand can also make getting ready much easier.
Then head out and enjoy the night. You don't have to stay out until 2 a.m.—unless you want to!
Don't Forget to Stay Hydrated
With all the sunshine, drinks, and walking around the ship, it's easy to forget the basics.
Drink plenty of water, reapply sunscreen throughout the day, and don't overdo it too early. You've still got the whole evening ahead!
It's simple advice, but after hours in the sun, you'll be glad you remembered it.
What If It Rains on a Sea Day?
A rainy sea day doesn't mean your day is ruined. Cruise ships have plenty happening indoors, and the crew may adjust the schedule when weather affects outdoor activities.
Look for trivia, game shows, live music, shows, classes, the casino, spa treatments, movies, dining, arcades, and other indoor activities. This is also when having a book, cards, or another simple activity comes in handy.
Sometimes a rainy sea day is exactly the excuse you need to explore parts of the ship you've been overlooking.
Are Sea-Day Activities Free?
Many sea-day activities are included in your cruise fare, but not everything is.
Pools, trivia, live music, production shows, and many recreational activities may be included. Other experiences—such as bingo, spa treatments, gambling, specialty dining, behind-the-scenes tours, arcades, and certain premium attractions—may cost extra.
Exactly what's included varies by cruise line and ship, so check before assuming something is complimentary.
The good news is that you can have an amazing sea day without spending anything extra.
The Best Part About Sea Days
There isn't a right or wrong way to spend a sea day.
Some people stay by the pool from sunrise to sunset. Others fill every hour with activities. And some simply enjoy doing absolutely nothing—and that's perfectly okay too.
That's the beauty of cruising. Your vacation can be as relaxing or as adventurous as you want it to be.
When you open your cruise line's app and see activity after activity after activity, don't feel like you need to do all of it. Pick a few things you really want to experience and leave room for whatever happens along the way.
We've had sea days where we've stayed busy from morning until night and others where we've spent hours doing almost nothing.
Both can be fantastic cruise days.
My Final Thoughts
Sea days aren't just the days between cruise ports. They're part of the vacation.
Whether your perfect sea day involves waterslides and trivia, brunch and cocktails, spa treatments and live music, or nothing more than a quiet chair and a good book, there's no single right way to spend it.
No rushing to catch an excursion. No alarm clock. No racing back to the ship before all aboard.
Just you, the ship, and an entire day at sea. ☀️
