The Caribbean cruise packing list looks simple until you're in Cozumel at noon without sunscreen or a waterproof bag. Here are the 12 things most first-timers wish they'd brought.
Packing for a Caribbean cruise looks simple and is frequently done wrong. It isn’t a beach vacation: you’re also packing for dinners, shore excursions, sea days, and maybe a night out, all from one suitcase, for a week, in tropical heat. And because onboard shops charge resort prices for basics like sunscreen, packing right the first time genuinely saves money.
This Caribbean cruise packing list covers what to pack for a cruise to the tropics. Here’s what most people forget, and why each one matters.
Water, lemonade, and iced tea are free at the buffet, but bottled water and sodas cost extra around the ship. Bring an insulated bottle (a 32oz Hydro Flask or a Stanley works well), fill it at the buffet each morning, and carry it to the pool deck or ashore. In Caribbean heat you need more water than you think, and this adds up to real savings over a week.
On snorkeling trips, beach days, or water taxis, your phone and documents are at risk. A 10L dry bag handles most shore days and costs around $15 on Amazon. Floating styles are worth the small upgrade in case one goes over the side. You’ll use it at every water port.
Two reasons to bring your own. First, many reef tours and marine parks, including those in Cozumel’s protected reef areas, ask for biodegradable, reef-safe sunscreen free of oxybenzone and octinoxate. Second, onboard sunscreen is marked up heavily. Pack two full bottles of a mineral formula such as Blue Lizard or Raw Elements, apply before you go ashore, and reapply often. Midday sun on the water burns faster than you expect.
You need something that holds your water bottle, sunscreen, phone, a light layer, and snacks. A packable daypack (like Osprey’s Ultralight Stuff Pack) folds to nothing. Choose one with a zipper so your things stay secure in port.
US dollars are widely accepted at Caribbean cruise ports, including the Bahamas and Cozumel, but small bills matter. Taxi drivers and beach vendors often can’t make change, and guides expect cash tips. Bring at least $100 in $1s, $5s, and $10s, more if you’re doing activities. Don’t count on port ATMs; fees are high and they can run dry on busy ship days.
Even people who never get seasick can feel an open-ocean crossing. The Caribbean is usually calm, but weather varies. Pack a less-drowsy meclizine option (Bonine or Dramamine Less Drowsy) for daytime and original Dramamine for night if needed. Many cruisers swear by prescription scopolamine patches, worn behind the ear for up to three days; ask your doctor before you go. The ship’s medical center sells remedies, at a markup.
Cabins usually have only a couple of outlets, often in awkward spots. A compact hub with USB ports charges phones, a camera, and an e-reader at once. The catch: cruise lines ban surge protectors because they can interfere with the ship’s electrical system, and some lines restrict extension cords too. Buy one labeled non-surge or “cruise approved,” and check your line’s prohibited items list. While you’re there, note that clothes irons and garment steamers are banned on the major lines; bring wrinkle-release spray instead.
Ship dining rooms and theaters are aggressively air-conditioned. You’ll sweat through a 90-degree shore day, then shiver through the evening show. A light cardigan or pashmina takes almost no space and makes evenings far more comfortable, whether you’re in the main dining room or the buffet.
Sounds ridiculous until you’ve lived in a cabin. Interior staterooms are small and bathroom counter space is nearly nonexistent. A clear organizer over the bathroom door gives you a couple dozen pockets for sunscreen, medications, chargers, and sunglasses that would otherwise pile up on the desk. They run about $12 to $15 on Amazon.
Most snorkel excursions include rental gear, but the masks are well used and rarely fit right. Your own traditional mask and snorkel means you actually enjoy the reef. Skip full-face masks, which some operators don’t allow. A mask and snorkel pack flat in a mesh bag; add fins if you have room, since they help a lot on longer swims.
Most Caribbean cruises have one or two dressier evenings in the main dining room (Carnival calls them “Cruise Elegant,” Royal Caribbean “Dress Your Best”). It’s not as strict as it used to be, but board shorts at a sit-down dinner still feel out of place. Men: a button-down, trousers, and non-sandal shoes. Women: a sundress that works for dinner covers most situations. Prefer to skip it? The buffet has no dress code.
If your phone dies at 4pm in Nassau and all-aboard is 4:30, you need to know your ship, cabin number, and where it’s docked. Write down your ship name, cabin number, all-aboard times, and the cruise line’s emergency number and keep it in your bag. Also double-check your ID. On closed-loop cruises (starting and ending at the same US port), US citizens can use a certified birth certificate plus a government-issued photo ID, but a passport is strongly recommended: without one, flying home from a foreign port after a missed ship or medical emergency gets very complicated. REAL ID alone isn’t a travel document for cruises.
Towels. The ship provides them, including pool towels you can take ashore (return them, or you may be charged).
Hair dryer. Nearly every cabin has one.
More than a week of toiletries. The ship shop can cover anything basic you forget.
A full medicine cabinet. Bring your prescriptions and trip basics. The medical center can handle simple needs, at a price.
Shoes for every outfit. Comfortable walking shoes, sandals you can dress up, and flip-flops cover basically everything on a 7-night Caribbean cruise.
At the terminal you hand your checked bags to a porter, and they’re delivered to your stateroom later in the day, often not until the afternoon or early evening. So pack your carry-on with your swimsuit, a change of clothes, medications, chargers, travel documents, and anything else you need for the first few hours. Unlike airport security, cruise terminals don’t limit toiletry liquids, so sunscreen can go in your carry-on (alcohol rules are separate and vary by line).
One well-packed carry-on and one checked bag is the sweet spot for a 7-night Caribbean cruise. For port-by-port tips, see our Cozumel and Nassau shore excursions guide, and if you’re still choosing a ship, start with our best cruises for first-timers.
Pack light, pack smart, and bring the dry bag. You’ll thank yourself at every port.
