Packing for a cruise is fundamentally different from packing for any other type of vacation — and most first-time cruisers get it wrong in the same ways. They either overpack (cruise cabins are cozy, not spacious) or they underprepare for the variety of activities and dress codes that come with seven days at sea.
After many Caribbean and other cruises between us, Melissa and I have developed a packing system that covers every scenario without requiring you to check three bags. Here's what that looks like.
Documents — Don't Leave Home Without These
Before we talk about what to wear, let's talk about what you absolutely cannot forget. This is the category where getting it wrong means not boarding the ship at all.
- Passport — even for domestic Caribbean cruises, carry your passport. A government-issued ID and birth certificate technically work for some itineraries, but a passport is the safest option and protects you if there's a medical emergency in a foreign port.
- Cruise confirmation and boarding documents — most cruise lines let you check in online. Print a copy or have digital access saved offline.
- Travel insurance documentation — if you have it (and you should), keep a copy in your carry-on.
- Credit card and ID — you'll link a card to your onboard account at check-in.
Clothing — The 7-Night Formula
A 7-night cruise typically has two formal or "smart casual" evenings, several casual evenings, and a full week of sea days and port days. Here's how we break it down:
- 2 formal/dressy outfits — for formal nights. Men: suit or sport coat and slacks. Women: cocktail dress or dressy separates. Black tie is rarely required, but putting in the effort is part of the fun.
- 5–6 casual evening outfits — slacks/jeans and a nice top for men, sundresses or casual separates for women. These can be mixed and matched.
- Daytime/resort wear — lightweight, breathable clothing for port days. Plan for heat and humidity in the Caribbean. Quick-dry fabrics are your friend.
- Swimwear — bring 2–3 options so one can always be drying. Swim cover-ups are useful for walking through the ship from the pool.
- One light jacket or layer — ships are aggressively air-conditioned. You'll want something for evenings inside and for theater shows.
- Comfortable walking shoes — for port days. You'll often walk several miles in a day. Break them in before the trip.
- Sandals or flip-flops — pool deck staples.
- One pair of dressier shoes — for formal nights.
Toiletries & Health Essentials
Ships have shops onboard, but prices are high. Stock up before you board.
- Sunscreen — lots of it. You will burn faster on the water than anywhere else. Reef-safe formulas are required in many Caribbean ports and better for the ocean.
- Motion sickness medication — even if you've never been motion-sick before. The open ocean on rough days can surprise you. Dramamine, Sea-Bands, and scopolamine patches are all worth having.
- Hand sanitizer — ships keep things very clean, but hand hygiene is important when you're in close quarters with a lot of people.
- Any prescription medications — bring more than you need in case of delays. Keep them in your carry-on, not checked luggage.
- Basic first aid kit — bandages, pain reliever, antacids, anti-diarrheal, and any personal medical needs. The ship has a medical center, but you don't want a blister from a port walk to derail your day.
- Your own shampoo/conditioner — ships provide toiletries, but many travelers prefer their own. Mini travel bottles save space.
Electronics & Gear
- Power strip or USB hub — cruise cabins typically have very few outlets. A small surge-protected power strip is a game-changer. (Note: no extension cords with surge protectors on some lines — check your cruise line's policy.)
- Waterproof phone case or camera — essential for beach and water excursions.
- Portable charger/power bank — useful for long port days when you're away from the cabin for hours.
- Earbuds or headphones — for sea days, the gym, or just quiet time on the balcony.
- Lightweight daypack — a small backpack for port days. You'll want to carry water, sunscreen, and purchases without being weighed down.
What to Leave at Home
This list is just as important as what to pack.
- Irons and clothes steamers — not allowed onboard. Most ships offer pressing services, or you can hang things in the bathroom while showering to remove wrinkles.
- Too many pairs of shoes — shoes are bulky and heavy. Three pairs (walking shoes, sandals, dress shoes) covers virtually every scenario on a Caribbean cruise.
- Valuables you can't afford to lose — expensive jewelry, heirlooms, anything irreplaceable. Leave it home.
- Full-size toiletry bottles — travel sizes and refillable containers save significant luggage space.
- Half your wardrobe — the biggest mistake first-time cruisers make. You won't wear it all, the cabin storage is limited, and laundry services are available onboard if needed.
One thing Melissa insists on: pack your first-day outfit, medications, travel documents, and a swimsuit in your carry-on. Checked bags are often delivered to your cabin hours after boarding. If you want to hit the pool deck immediately — and you will — you'll be glad you planned ahead.
The Day-Before Checklist
The night before departure, run through this quick list to make sure you haven't forgotten anything critical:
- Passport and travel documents — in your carry-on bag
- Medications — in carry-on, more than needed
- Phone chargers and cables
- Sunscreen and motion sickness medication accessible
- Credit card and some cash in local currency if visiting non-USD ports
- Cruise line app downloaded on your phone
- Shore excursion confirmation numbers saved
Cruising is one of the most fun, relaxed, and immersive ways to travel — and a little preparation goes a long way toward making sure the experience is exactly as smooth as it should be.
