A cruise is three vacations in one — a beach resort, a nice restaurant, and a hiking trip — which is exactly why packing for one feels so confusing. Your suitcase has to cover formal dinners, pool days, port excursions, and a tiny cabin with almost no storage. Get it right and the week feels effortless; get it wrong and you're buying an overpriced sundress in the ship's gift shop.
This cruise packing list covers all of it: what to wear for formal nights, excursion gear for port days, the cabin essentials experienced cruisers swear by, and — just as important — the items cruise lines ban outright. It works for Caribbean, Alaska, and Mediterranean sailings, with notes on where they differ.

Cruise Documents (Don't Board Without These)
Cruise lines are stricter about documents than airlines, because the ship visits multiple countries.
- Passport — required for most cruises, even "closed-loop" sailings from US ports. Some lines accept a birth certificate + government ID on closed-loop Caribbean cruises, but a passport is faster at every port and required if you ever need to fly home mid-trip from a foreign port.
- Boarding pass and luggage tags — complete online check-in before you leave home and print your boarding pass. Attach the cruise line's luggage tags to every bag before you hand them to porters.
- Travel insurance documents — medical evacuation from a ship can cost $50,000+. Carry your policy number and the assistance line.
- Credit card for your onboard account — everything on the ship runs through your room key card, settled against a credit card you register at check-in.
- Vaccination records — requirements change by itinerary; check your cruise line's health page 2 weeks before sailing.
- Shore excursion confirmations — printed or saved offline, with meeting times and locations.
Take a photo of your passport's data page and email it to yourself. If the original is lost in port, that photo plus a trip to the nearest US embassy gets you home.
Formal Nights: What to Actually Wear
Most 7-night cruises have 1–2 formal or "dress your best" nights. The dress code has relaxed a lot — but showing up in shorts still gets looks.
For women:
- 1–2 cocktail dresses or a dressy jumpsuit
- Dressy sandals or low heels (remember: the ship moves — very high heels are a hazard)
- A wrap or shawl (dining rooms are heavily air-conditioned)
- One statement piece of jewelry; leave the expensive stuff in the cabin safe
For men:
- Dark suit or blazer + dress pants + collared shirt (a full tuxedo is unnecessary on most lines now)
- Tie optional on most mainstream lines (Royal Caribbean, Carnival, Norwegian); more expected on luxury lines
- Dress shoes
The rest of the evenings are smart-casual: collared shirts or nice blouses, slacks or skirts, no swimwear or tank tops in the main dining room. Pack 3–4 smart-casual dinner outfits for a 7-night sailing. One packing trick: a black dress or a navy blazer works for both formal night and a regular dinner with different accessories — nobody remembers.
Daytime and Port Day Clothing
- 4–5 casual tops (t-shirts, tanks, breathable fabrics)
- 2–3 shorts or skirts
- 2 swimsuits (one always drying)
- 1 cover-up that doubles as a port-day top
- 1 light jacket or hoodie (ship decks get windy; Alaska cruises need a real warm layer)
- Walking sandals + water shoes (rocky beaches and reef entries demand them)
- 1 pair of comfortable closed-toe walking shoes for excursions with uneven terrain
- Sun hat and sunglasses
- Workout clothes (1–2 sets) if you use the ship's gym
Alaska difference: swap shorts for jeans and hiking pants, add a waterproof rain jacket (Southeast Alaska gets 100+ inches of rain a year in places), fleece mid-layers, and a warm hat and gloves for glacier viewing days. The temperature swing between a sunny deck and a glacier viewpoint can be 30°F.
Cabin Essentials Experienced Cruisers Swear By
Cruise cabins are small — a standard interior room is about 150–185 square feet — with limited outlets and almost no counter space. These cheap items fix that:
- Magnetic hooks (4–6) — cabin walls are metal. Hooks hold hats, lanyards, excursion tickets, and wet swimsuits. This is the number one cruiser recommendation for a reason.
- Non-surge-protected power strip or multi-plug adapter — cabins often have just 1–2 US outlets. Critical: it must be NON-surge-protected, because surge protectors are confiscated (more on banned items below). A simple 3-outlet tap or a USB multi-charger works.
- Over-the-door shoe organizer — hangs on the bathroom door and holds toiletries, sunscreen, medications, and small items. Instant counter space.
- Nightlight — interior cabins are pitch black. A small plug-in or battery nightlight saves you from stubbing toes at 3 a.m.
- Lanyard for your room key — your key card is your wallet, ID, and room key. A lanyard keeps it on you at the pool.
- Small first-aid kit — band-aids, seasickness tablets, pain reliever. The ship's medical center charges for basics.
- Ziplock bags (assorted sizes) — wet swimsuits, sandy items, phone protection on excursions, leftover pastries from the buffet.
- Travel alarm clock or watch — ship time doesn't always match port time or your phone's auto-updates. Missing the all-aboard time means the ship leaves without you.
Toiletries and Health
Cabins provide basic soap and shampoo, but the quality is hotel-grade at best:
- Your preferred shampoo, conditioner, and body wash (travel sizes)
- Sunscreen — bring more than you think. Ship stores charge $18–25 for a bottle you could buy for $10 at home. One 8 oz bottle per person per week is the minimum for beach itineraries.
- Aloe vera gel
- Insect repellent for Caribbean and Mediterranean ports
- Prescription medications in original bottles + seasickness remedy (bonine/meclizine or acupressure bands — start them before you feel sick)
- Hand sanitizer
Excursion Gear by Port Type
- Beach/snorkel days: reef-safe sunscreen, water shoes, dry bag for phone and cash, underwater camera or waterproof phone pouch
- City/walking tours: daypack, refillable water bottle, portable phone charger, comfortable broken-in walking shoes
- Adventure excursions (zip-lining, ATV, hiking): closed-toe shoes, small backpack, bug spray, a change of clothes left on the ship
- Glacier/nature viewing (Alaska): binoculars (8x42 is ideal — the ship may rent them, but yours are better), warm layers, waterproof outer layer, camera with zoom
Book excursions through the cruise line or a reputable independent operator with a guaranteed return-to-ship policy. Independent tours are often 30–50% cheaper, but if a non-ship tour runs late, the ship will not wait.
What NOT to Pack: Banned Items
Cruise lines confiscate these at embarkation — no exceptions, no refunds:
- Irons and steamers — fire hazard. Every ship has laundry/pressing services; irons are the most confiscated item in cruising.
- Candles and incense — open flame, banned fleet-wide.
- Surge-protected power strips — the surge protection component is a fire risk on ship electrical systems. Non-surge strips and USB hubs are fine.
- Weapons of any kind, including pocket knives and multi-tools with blades
- Alcohol — policies vary: most lines let you bring 1–2 bottles of wine at embarkation (often with a $15–25 corkage fee); spirits and beer are confiscated. Check your line's exact policy.
- Drones — usually banned from use on the ship; some lines allow them in port only.
- Heating appliances — coffee makers, hot plates, heating pads with auto-shutoff sometimes allowed, check first.
Also leave behind: beach towels (the ship provides them, including for port days), hair dryers (in every cabin), and formal wear beyond the 1–2 outfits — the "elegant night" photo package is optional.
Embarkation Day Bag
Your checked luggage may not reach your cabin until evening. Pack a day bag with:
- Swimsuit and cover-up (pools are empty on embarkation day — the best swim of the trip)
- Sunscreen
- Medications
- Documents
- Phone charger
- A change of clothes for dinner
I plan every sailing port by port before I pack — the Alaska Cruise Planner has an excursion planning section where I list each port day's activity first, then build the packing list from that. Packing from the itinerary instead of from anxiety is what keeps the suitcase reasonable.
| Sailing type | Formal nights (7-day) | Key extra item | Biggest packing mistake |
|---|---|---|---|
| Caribbean | 1–2 | Extra sunscreen | Too many "nice" outfits |
| Alaska | 1–2 | Rain jacket + binoculars | Underestimating the cold |
| Mediterranean | 1–2 | Modest cover-ups for churches | Uncomfortable new shoes |
