Sea days sound like a dream. No schedule. Nowhere to be. Just the ocean, the pool, and your people.
And then 9am hits and your 5-year-old is already bored, your 8-year-old is hungry again, and someone is complaining that their goggles hurt.
That was us on our Disney Fantasy Merrytime Cruise during Thanksgiving 2025. We had a sea day right after Thanksgiving, and it went well because we had the right stuff with us. Our kids, Emery (8) and Kylo (5), went from the main pool to the kiddie pool to kids club, all without a single meltdown. And yes, there was a baby race. I’ll get to that.
Sea days are only overwhelming when you’re not prepared for them. Here is everything I’d pack again.
Quick Sea Day Essentials Checklist
Before we get into the details, here’s the full list at a glance. Save this before you pack.
Pool and water
Quiet time
Snacks and hydration
- Owala FreeSip reusable water bottle
- Easy grab-and-go snacks
- Reusable leakproof snack containers
Small but mighty
Between the pool, kids club, and a few things in your bag, sea days mostly take care of themselves. The key is a backup plan for when kids are too tired to swim but not ready to nap. That is when a downloaded show or a round of UNO earns its place in your bag.
None of these are hard to find or expensive. Most of them are things you probably already own or can grab on Amazon before you board. I’ll break down each category below with what worked for us and what I’d buy again.
One of these categories has a tip at the end of this post that I almost didn’t include. Spoiler: it involves dish soap.
Pool and Water Essentials
After breakfast on our sea day, Emery and Kylo went straight to the main pool. Frozen was playing on the big deck screen while they splashed around, then we moved to the kiddie pool overlooking the ocean. It was honestly stunning. Like an infinity pool, but with a 5-year-old doing cannonballs into it.
Here’s what made the pool situation work without turning into a mom scramble:
| Item | Why it matters |
| Reef-safe sunscreen stick | Disney ships require reef-safe. We brought our own so we weren’t scrambling or overpaying onboard. |
| Swim goggles | Kylo would not have survived the pool without these. Kids who can see underwater stay in the water longer, which buys you approximately 20 more minutes of peace. |
| Coverups or rash guards | Good for sun protection between pool dips and for kids who run cold when they get out of the water. |
| Water Shoes | Pool decks get hot and slippery. Water shoes are the move so kids can go in and out without the whole production. |
| Wet/dry bag | For soaked suits and towels on the walk back to the cabin. This one thing saved our dry bag situation every single day. |
One thing I’d add: we had the kids wear their swimsuits under their clothes on embarkation day, and that habit carried over. It made sea day mornings so much easier because they were basically ready to jump in before breakfast was even finished.
The kiddie pool on the Fantasy was something else entirely. I’ll describe it in the recap section below because it needs its own moment.
Quiet Time and Downtime Items
Kids will eventually hit a wall on a sea day. Waterlogged, sun-tired, and somehow still not ready for a nap. That in-between stretch is where you need a plan.
We dropped the kids at kids club for a few hours so the adults could actually see the ship. But before that, a few cabin items made the quiet stretches work. No screen guilt. We were on vacation.
- Amazon Fire Kids Tablet — download everything before you board. Ship wifi is slow and expensive. We used ours more than I expected, zero regrets.
- Volume-limiting kids headphones — get the kind that cap at 85 decibels. Your ears in a small cruise cabin will thank you.
- UNO mini — zero space, works for all ages, pulls in adults too. We played on the balcony and it ended up being one of the highlights of the trip. The real highlight though? That comes later. Keep reading.
Snack and Hydration Essentials
Disney ships have food everywhere, and the pool deck ice cream is as good as it sounds. But having your own snacks and water still matters, especially with kids who are hungry on a schedule that doesn’t match the buffet.
- Owala FreeSip water bottle, one per person — one of the best decisions we made for the whole trip. Refilled them every day. Kids loved having their own.
- Reusable snack containers — more useful than they sound. The real move is using them for cruise food. Grab fries or fruit from the buffet and relocate to a quieter spot on the ship. Sea days get crowded and being able to move your food is genuinely helpful.
Small Items That Make a Big Difference
- Anker magnetic portable charger — the Disney Cruise app, camera, and a tablet will drain your phone fast. You need this. (And you’ll need it charged for the baby race. More on that below.)
- Cruise lanyards — Emery and Kylo each had their own and loved wearing them. Key cards accessible, no digging through the bag every time you want back in the cabin.
- Magnetic hooks — cabin walls are magnetic. We hung wet towels, swimsuits, and lanyards so nothing ended up on the floor.
- Waterproof tote — one bag to hold all of it. Folds flat when you don’t need it.
What We Actually Used Most
Our sea day was the day after Thanksgiving. No agenda, 20 family members, and nowhere to be.
The kids were at the main pool by 9am, watching Frozen on the deck screen with ice cream in hand (yes, before noon, vacation rules). Then we moved to the kiddie pool that overlooked the ocean. It genuinely looked like an infinity pool. I stood there for a minute just taking it in.
We dropped the kids at kids club and the adults wandered the ship. That’s when the baby race happened. One of our family friends entered her crawling baby, Lando. The crowd was huge. He was doing great until he realized everyone was staring at him, and then he cried for his mom. He did not win, but he absolutely won our hearts though.
Then came the raffle at the jewelry store. Instead of our whole group of 20 waiting for the drawing, we gave all our tickets to Braxton, our teenage family member. He won a gold heart necklace and was so excited the whole group celebrated with him. The portable charger is how we got the whole thing on camera without a dead phone.
That evening we played UNO on the balcony while the sun went down. No plan, just cards and ocean air. One of my favorite moments of the whole cruise.
The five things we used all day:
- Reef-safe sunscreen stick
- Owala FreeSip water bottle
- Anker magnetic portable charger
- Cruise lanyards
- Wet/dry bag
If you only grab five things off this list, make it those.
Sea Day FAQs
Still have questions? I have one more tip at the very end of this post that I almost left out. First, the most common questions I get about sea days with kids.
A lot. Main pool, kiddie pool, AquaDuck (on ships that have it), kids club, deck movie screenings, character meet and greets, and organized activities all day. The ship does not run out of things to do. Your job is just keeping the transitions smooth.
Yes, and download everything before you board. Ship wifi is slow and expensive. An Amazon Fire Kids Tablet loaded with shows and games is one of the best cabin investments you can make.
Yes. Drinks and snacks from home are generally allowed, but always check Disney Cruise Line’s current policy before you pack. We used reusable containers to grab buffet food and relocate somewhere quieter. That trick saved us more than once.
Yes, and they fill up fast. Get there early for chairs, or head to a smaller pool later when crowds thin out. The kiddie pool on the Fantasy was a great call for younger kids and felt way less chaotic than the main pool.
Between the pool, kids club, and a few things in your bag, sea days mostly take care of themselves. The key is a backup plan for when kids are too tired to swim but not ready to nap. That is when a downloaded show or a round of UNO earns its place in your bag.
One Last Thing
Okay, here’s the tip I almost left out.
Pack a tiny bottle of dish soap. When you’re using reusable containers to grab cruise food all day, you’ll want to rinse them out in the cabin. Dish soap and a paper towel takes 30 seconds. No gross bags sitting in the corner. Clean container ready for tomorrow.
No packing list ever tells you this. Now you know.
Quick recap:
- Reef-safe sunscreen and goggles for the pool
- Downloaded tablet and headphones for quiet stretches
- Water bottles and snack containers for all day
- Wet bag, lanyards, charger, and magnetic hooks for everything else
- A tiny bottle of dish soap because now you know
Sea days are some of the best days on a Disney cruise. With the right bag, you’ll spend a lot less time managing and a lot more time actually being there.
