First Cruise with Kids? Exactly What to Pack (and What to Skip)

Our first cruise was a 4-night out of Port Canaveral. I packed like we were moving to sea permanently. Two full-size suitcases per person. A separate "pool bag." A duffle of snacks roughly the size of a toddler. I brought a STEAMER — like, a garment steamer — because I read on some cruise forum that formal night wrinkles are a thing. Know what happened? We spent the first two hours in the cabin trying to figure out where to PUT everything. Cruise cabins are about the size of a large closet. Our suitcases were literally stacked on each other in a tower next to the balcony door, and every time someone wanted to go outside they had to climb over luggage like it was an obstacle course. By cruise number three — a 7-night Western Caribbean on Royal — I'd figured it out. The trick with cruising is that it's actually EASIER to pack for than most trips, because the ship provides so much. You just have to know what's already there. Here's everything I've learned, organized the way I wish someone had told me before that first sailing. This post contains affiliate links.

Embarkation Day Carry-On (The Bag That Saves Your Sanity)

This is the single most important thing nobody told me about our first cruise. When you board, your checked luggage goes to the porters at the terminal and it gets delivered to your cabin... eventually. Could be 1 PM. Could be 4 PM. Could be 6 PM if you board early and the ship is still loading. You will not see your suitcases for HOURS. Meanwhile, the pools are open, the buffet is calling, and your kids are vibrating at a frequency only dogs can hear. You need a carry-on bag that has everything for the first 4-6 hours on the ship. Here's what goes in ours:

• Swimsuits + cover-ups for everyone — the pool deck opens before your cabin luggage arrives

• Sunscreen — SPF 50 minimum, reef-safe for Caribbean ports (Sun Bum SPF 50 $15)

• One change of clothes per kid — someone WILL get soaked before the suitcases show up

• Medications — everything prescription, plus kid's Tylenol, Dramamine, Band-Aids. Don't put meds in checked luggage. Ever.

• Phone chargers + a power bank

• Cruise documents + IDs — boarding passes (printed — don't rely on the app), passports if needed, birth certificates for kids on closed-loop cruises

• Valuables — jewelry for formal night, anything you'd cry about losing

• An empty reusable water bottle — fill on the ship, carry to ports

• Snacks — the buffet will be there, but the check-in line can take 45 minutes and hangry kids in a queue is its own kind of suffering

We use one Brevite Jumper Backpack ($135) as the family carry-on and each kid carries a small backpack with their tablet and headphones.

Cabin Essentials (The Stuff That Makes a Tiny Room Livable)

Cruise cabins average about 180 square feet. With four people, you need to think vertically. These items are non-negotiable.

Magnetic Hooks

Cruise cabin walls are metal. ALL of them. Heavy-duty magnetic hooks ($12 for a 10-pack, look for 40+ lb pull force) go on the walls, ceiling near the closet, bathroom door frame. We hang hats, wet swimsuits, lanyards, backpacks — anything that would otherwise live on the floor. I bring 10 hooks minimum.

Power Strip (Non-Surge)

Most cabins have 1-2 outlets. For a family with phones, tablets, and a power bank, that's a comedy of errors. The Anker PowerPort ($26) has 4 USB ports and 2 AC outlets. It's cruise-approved because it's NOT a surge protector — surge protectors are banned on every major line.

Nightlight

Cruise cabins get DARK. When your kid needs the bathroom at midnight, you either packed a nightlight or everyone's awake. We use a plug-in motion-sensing nightlight ($8) in the bathroom and magnetic LED puck lights ($10 for a 3-pack) near each kid's bed.

Over-Door Hanging Organizer

A clear pocket over-door organizer ($13 at Target) hangs over the bathroom door. Sunscreen, toothbrushes, hair ties, goggles, room key cards — everything visible, everything off the 18-inch counter that would otherwise be buried by day two.

Other Cabin Must-Haves

• Packing cubes — for keeping clothes organized in those tiny drawers all week. One cube per person. (Peak Design $40 large)

• Mesh laundry bag ($5) — hang it on a magnetic hook. Dirty clothes go in, not back in the suitcase.

• Waterproof phone pouch ($8 for a 2-pack) — for the pool deck and water excursions

• Downy Wrinkle Releaser Travel Size ($4) — irons are banned on cruise ships, and formal night clothes WILL be wrinkled from the suitcase

• Lanyard for cruise cards ($5 for a 4-pack) — kids lose room keys approximately every 45 minutes. A lanyard around the neck solves this. Dorky? Sure. Effective? Very.

Clothing by Day Type

Here's where first-time cruisers either way overpack or way underpack. The key is understanding that not every day on a cruise is the same — and packing by day type instead of by outfit keeps things manageable. For a 7-night cruise, you'll typically have:

• 2-3 sea days (on the ship all day)

• 2-3 port days (off the ship exploring)

• 2 formal/dressy nights (dinner in the main dining room)

• Pool time almost every day regardless

Sea Days

Lazy days. Pool, buffet, kids' club, maybe the waterslide 47 times. Swimsuit + cover-up IS the outfit until dinner. Comfortable shorts and a tee for evening. Flip-flops.

Port Days

Walking excursions, beach stops, snorkeling. Lightweight shorts, breathable top, walking shoes or sport sandals — Teva Hurricanes ($70) work great for water + walking ports. Swimsuit underneath if it's a beach stop. Leave valuables on the ship in the safe.

Formal Nights

Every cruise has 1-2 of these. The dress code is flexible. You don't need a tuxedo, but you can't show up in your pool cover-up. Adults: A nice dress or button-down with chinos. One outfit covers both nights — nobody remembers what you wore Tuesday. Kids: A polo with khakis. My son wore the same navy polo both formal nights. My daughter brings one "twirly dress" (her words) and is THRILLED about dinner. Worth the suitcase space for that smile.

Pool Days (Every Day, Basically)

2 swimsuits per person — this is the hill I will die on. One swimsuit in a cruise cabin takes 12+ hours to dry. There's no outdoor clothesline, the cabin is climate-controlled, and a damp suit at 6 AM is nobody's idea of fun. Two suits, rotate daily, problem solved. Add a rash guard for kids ($15 at Target) — saves constant sunscreen reapplication on waterslides.

The Actual Count (7-Night Cruise)

| Item | Adults | Kids | Notes | |------|--------|------|-------| | Casual tops | 5 | 5 | Mix and match with bottoms | | Casual bottoms | 3 | 3 | Shorts, skirts, or pants | | Swimsuits | 2 | 2 | Rotate daily — they won't dry | | Formal outfit | 1 | 1 | Rewear for both nights | | Underwear | 7 | 8 | Kids get one extra. Trust me. | | Socks | 4 | 4 | You mostly wear sandals | | Pajamas | 1 | 1 | | | Light jacket or hoodie | 1 | 1 | Dining rooms run cold | | Shoes — walking | 1 | 1 | Worn during travel | | Shoes — sandals/flip-flops | 1 | 1 | | | Shoes — dress (adults) | 1 | 0 | Kids wear clean sneakers | | Rash guard | 0 | 1 | | That's it. Seriously. You have access to laundry on the ship (more on that in the carry-on packing guide) and you're wearing a swimsuit for half the day anyway.

Kids-Specific Packing

Some of this depends on ages, but here's what I've learned across three cruises with mine (my youngest was in pull-ups on the first one — now they're carrying their own backpack). Toddlers/Babies: Bring your own swim diapers — the ship gift shop sells them for approximately the price of gold. Huggies Little Swimmers ($12 for 20), pack 4-5 per pool day. Most cruise lines provide a crib free if you request it at booking. Bring an umbrella stroller ($25-40) instead of full-size — easier through the gangway. Our Summer Infant 3Dlite ($70) survived all three cruises. School-Age Kids: Tablet + headphones are essential — load movies BEFORE you board because ship Wi-Fi streams like it's 2007. One small activity kit for cabin downtime. A reusable water bottle with a clip — one without a clip ends up at the bottom of the pool. And snacks. I know the ship has food 24/7, but between the cabin and the buffet is a 10-minute walk, and a 6-year-old's blood sugar doesn't negotiate. Granola bars, goldfish crackers, sealed and pre-packaged. Teens: Let them pack their own stuff, give them the clothing count from the table above, and bring a power strip because they will want to charge seventeen devices simultaneously.

What the Cruise Provides (So You DON'T Pack It)

This part would have saved me two entire suitcases on cruise #1. The ship already has:

• Towels — cabin AND pool towels. Grab pool towels on the way out, drop them in the bin on the way back. Do NOT bring beach towels.

• Shampoo, conditioner, body wash — stocked in the cabin. If you're particular, bring travel-size. Not full-size.

• Hair dryers — mounted to the wall. They're terrible — like a hamster breathing on your hair — but they exist.

• Room service breakfast — included on most lines. No need to pack breakfast bars.

• An in-room safe — for passports, jewelry, extra cash.

• Kids' club supplies — art supplies, games, the works. Don't pack a craft kit.

• Laundry facilities — self-service rooms on Disney, Celebrity, Carnival, Holland America. Royal Caribbean is the notable exception — no self-service laundry. Check your line before you sail.

• Irons — just kidding, these are banned. But the wrinkle releaser I mentioned handles it.

What to Skip (Common Cruise Overpacking Mistakes)

These are things I packed on cruise #1 that never left the suitcase. Books. Plural. I brought four paperbacks like I was going to have eight free hours to read while my kids were... where, exactly? ONE book or a Kindle. Formal shoes for the kids. Clean sneakers are fine. My daughter's light-up Skechers went to formal night and she got compliments. Full-size toiletries. The cabin bathroom is the size of an airplane bathroom. Travel size everything. A garment steamer. (Yes, I really packed this.) The $4 wrinkle releaser spray works just as well. Snorkeling gear. Rent at the port for $10-15. Masks and fins eat suitcase space. A separate "excursion bag" and "pool bag" and "port bag." You need ONE day bag. A backpack. Stop packing single-purpose bags.

The Packing Timeline (When to Start, How to Stay Organized)

I used to throw everything in the suitcase the night before. Now I have a system. 2 weeks before: Check the weather forecast for your itinerary ports. Order any cabin essentials you don't have (magnetic hooks, power strip, nightlight). Start a list — I use TripTiq to build mine because it knows the weather and factors in cruise-specific stuff, but even a notes app works. The point is to start early instead of panic-listing at midnight. 1 week before: Do laundry so everything you want to pack is actually clean (this sounds obvious but I have forgotten). Lay out clothing by day type: sea days, port days, formal nights. Pack the cabin essentials bag. 2-3 days before: Pack everything except what you'll wear on embarkation day and your toiletries. Assemble the embarkation carry-on. Print boarding documents — the app sometimes crashes when 3,000 people are trying to check in simultaneously. Night before: Add toiletries and chargers. Set out embarkation day clothes. Put the carry-on by the front door. Take a photo of each packed suitcase, open, contents visible — documentation if anything gets lost. Embarkation morning: Toss in the last toiletries. Grab the carry-on. Resist the urge to throw in "one more thing." The suitcase is closed. Walk away.

FAQs

What should I pack in my cruise carry-on bag?

Swimsuits, sunscreen, medications, one change of clothes, phone charger, and any valuables. Your checked luggage may not arrive at your cabin until 3-4 PM on embarkation day. This bag is your lifeline for the first several hours on board.

Can you bring a power strip on a cruise?

Non-surge-protector power strips are allowed on most cruise lines. The Anker PowerPort ($26) is compact and cruise-approved. Surge protectors are banned on all major lines — they're a fire hazard. If the packaging says "surge protector" anywhere on it, leave it home.

How many outfits should I pack for a 7-day cruise?

Plan for one outfit per day plus 2 formal night outfits. Kids can rewear casual clothes — nobody notices. Bring 2 swimsuits per person because they take forever to dry in a climate-controlled cabin. You're eating with different people most nights. Nobody is tracking your wardrobe.
