What to Actually Pack for a Caribbean Cruise

The internet's cruise packing lists are written by people who have never carried a suitcase up a gangway. They'll tell you to bring eleven outfits and a portable fan.

Here's the realistic version for seven nights in the Caribbean, from someone who has watched a lot of families over-pack.

The one rule that matters

Your cabin is small. Genuinely small - a standard interior is around 150 square feet, for two people, for a week. There's storage under the bed and in a narrow closet, and that's it. Every unnecessary item you bring is something you shuffle around for seven days.

Pack for four days and use the laundry service or the self-serve machines. Most lines run a "fill this bag for $35" special mid-cruise, and it is worth every penny.

Clothes

3-4 swimsuits. More than you think, fewer than you'd pack. They don't dry overnight in a humid cabin, so you want rotation.
A cover-up and flip flops. You can't walk through the buffet in just a swimsuit on any line.
4-5 casual daytime outfits. Shorts, tees, sundresses. Light colors, breathable fabric.
2-3 dinner outfits. "Cruise casual" on most lines means a collared shirt or a sundress. Nothing dramatic.
One dressier outfit if your line still does a formal or "elegant" night - usually one or two per week. Skip the tux; a jacket is plenty.
A light jacket or wrap. This is the one people forget. Ships run the air conditioning aggressively, and the theater and dining room are cold.
Comfortable walking shoes. Port days involve far more walking than you plan for.
Water shoes if you're doing any rocky beaches or reef snorkeling.

The things people forget every single time

Magnetic hooks. Cabin walls are steel. Hooks turn a wall into storage for hats, bags, and wet swimsuits, and they cost almost nothing.
A power strip with no surge protection. Cabins have very few outlets. Surge-protected strips are confiscated - a plain one or a USB hub is allowed on most lines. Check your line's rules.
Motion sickness remedies. Bring them even if you've never been seasick. The ship's shop charges a fortune and the medical center charges more.
A refillable water bottle. Port days get hot fast.
Sunscreen, more than you think. Reef-safe if you're snorkeling, and buy it at home - onboard prices are painful.
A lanyard for your cruise card. It's your room key, your payment method, and your ID for getting back on the ship.
Over-the-door shoe organizer. Sounds silly. Doubles your bathroom storage. Every experienced cruiser packs one.
Downloaded entertainment. Assume no usable internet.

What they'll take off you at the terminal

Security scans every bag at check-in, and these come out:

Surge-protected power strips and extension cords
Irons, steamers, and travel kettles
Candles and incense
Space heaters and hot plates
Drones (banned on most lines)
Alcohol beyond the line's allowance - typically one bottle of wine per adult at embarkation, and nothing at all on some lines
Anything that looks like a weapon, including some multi-tools

Confiscated items are usually held and returned on the last night, but not always. Don't pack anything you'd hate to lose.

Documents - the non-negotiable pile

Passport (check the expiration date now, not the week before)
Birth certificates for children, if you're sailing on those instead
Printed boarding pass and luggage tags
Travel insurance policy number and the 24-hour assistance line
A printed copy of your flight and hotel confirmations
A credit card, and a backup card kept somewhere separate

Photograph all of it and email the photos to yourself. It takes two minutes and it has saved more vacations than any other single habit.

What to leave home

Beach towels. The ship provides them, at the pool and for going ashore.
Hair dryer. Every cabin has one. It's mediocre, but it exists.
Formal wear, unless you genuinely enjoy it. Cruise dress codes have relaxed enormously.
Expensive jewelry. Cabin safes are small and not that secure.
Your third pair of shoes. Two pairs plus flip flops. Truly.

I keep a printable version of all of this - organized by category, with the prohibited items list on the back - in the free travel resources. Print it, check things off, and stop packing at four days' worth.
