Start with the cruise line's packing rules and your itinerary

Before you pack a single item, check your cruise line's website for their specific packing rules. Most lines have restrictions on what you can bring into your cabin — things like irons, candles, surge protectors with outlets, and alcohol purchased outside the ship are commonly banned. Your booking confirmation or the cruise line's app will list these rules.

Next, look at your actual itinerary. A seven-day Caribbean cruise where you dock at warm ports every day requires different clothing than an Alaska cruise with sea days and glacier viewing. Check the weather forecast for each port and note whether you'll be doing formal dinners, casual buffets, or excursions that require specific gear. A river cruise in Europe has different dress codes than a party-focused Caribbean sailing.

Write down your cabin type too. Inside cabins have no windows, so you won't need blackout curtains, but you might want a small nightlight. Balcony cabins mean you'll want a light jacket for evening air. Suites often have more storage, so you have more flexibility.

Key Takeaways

  • Check your cruise line's prohibited items list before packing anything — most ban irons, candles, extension cords, and outside alcohol.
  • Pack clothes for the actual weather at your ports and the ship's dress code, which typically ranges from casual daytime to formal or smart-casual dinners.
  • Bring medications in their original labeled bottles, copies of prescriptions, and a list of what you take — cruise ships have doctors but limited pharmacy stock.
  • Pack toiletries in carry-on luggage in 3.4-ounce bottles if you're flying, and bring any specialty items the ship's small shop won't stock.
  • Leave room in your luggage for purchases and souvenirs, or plan to check a bag on the return flight.

Clothing for sea days and port days

Most cruise lines divide their dress code into three categories: casual (daytime and casual dinners), smart-casual or elegant (nicer dinners), and formal (usually one or two nights on longer cruises). Check your confirmation email or the cruise line's app to see which nights fall into each category. You do not have to dress up — casual dining is always available — but knowing the code helps you pack appropriately.

For daytime, pack lightweight, breathable clothing. Shorts, t-shirts, sundresses, and casual pants work for most cruises. Bring at least one pair of comfortable walking shoes for port days and one pair of sandals or flip-flops for the pool deck. If you're visiting cooler ports or taking an Alaska cruise, pack layers: a light sweater or fleece and a windbreaker or rain jacket.

For dinners, bring two or three outfits that fit the dress code. Smart-casual typically means dress pants or a nice skirt with a blouse, or a sundress with a cardigan. Formal means a suit, dress, or dressy separates. Men often wear dress pants and a button-up shirt for smart-casual, and a suit or tuxedo for formal. Bring comfortable dress shoes — you'll be walking on the ship and in ports.

Pack one swimsuit minimum, but two is better so one can dry while you wear the other. Bring a cover-up or light shirt for the pool deck and a rash guard if you sunburn easily. Include a pair of water shoes if you plan to snorkel or walk on rocky beaches.

Toiletries, medications, and personal care items

Cruise ships have small shops that sell basic toiletries at high prices. Bring your own shampoo, conditioner, body wash, toothpaste, and deodorant in quantities that match your trip length. Most cabins provide basic soap and shampoo, but many people prefer their own products.

Pack all medications in their original labeled bottles with your name on them. Bring a written list of your medications, dosages, and the conditions they treat — if you need a refill or have a medical emergency, the ship's doctor will need this information. Pack prescription medications in your carry-on luggage if you're flying, never in checked bags. Bring extra doses in case your return is delayed.

Include a small first-aid kit: adhesive bandages, pain relievers, antacids, anti-diarrhea medication, antihistamines, and any personal medications like inhalers or EpiPens. Bring sunscreen — the ship's shop sells it, but it's expensive and may run out on sunny days. Pack any specialty items you use regularly: contact lens solution, specific skincare products, or prescription glasses or contacts.

Women should pack feminine hygiene products in the quantity they expect to need. While ships carry these items, selection is limited and prices are high. Bring a small sewing kit, nail clippers, and any hair styling tools you use — the ship's cabin may have a hair dryer, but it's often low-powered.

Documents and money

Bring your passport or passport card if you're leaving the United States, even for a short Caribbean cruise. Some cruises visit only U.S. ports and accept a Real ID driver's license, but check your specific itinerary. Make a photocopy of the main page of your passport and store it separately from the original.

Bring your cruise line's booking confirmation and any pre-purchased shore excursion vouchers. Most ships now use a keycard system that also functions as your onboard account — you'll link a credit card to it during check-in. Bring at least one credit card and a small amount of cash for tipping and small purchases at ports where cards may not work.

Pack travel insurance documents if you purchased a policy. Bring copies of any medical records or vaccination records if required by your ports. Store digital copies of important documents in your phone or email so you can access them if you lose the physical copies.

Electronics and charging

Bring your phone charger and any chargers for tablets, cameras, or other devices. Most modern cruise cabins have USB ports and standard electrical outlets, but older ships may have limited outlets. A power strip or multi-outlet adapter is banned on most cruise lines, but a USB charging hub is usually allowed — check your cruise line's rules.

Pack a portable phone charger if you plan to spend long days exploring ports without access to your cabin. Bring a camera if you prefer it to your phone, along with extra memory cards and batteries. Most ships have spotty Wi-Fi that you can purchase by the day or week, so read any entertainment, maps, or documents you might need offline.

Consider bringing a small flashlight or headlamp. Cabin hallways are dimly lit at night, and a light helps you find your keycard slot and navigate safely. A small portable speaker is useful for playing music in your cabin, though check your cruise line's rules about noise levels.

Optional items that make cruising more comfortable

Bring a reusable water bottle. Most ships have water fountains and will fill bottles for free, saving you money on bottled water. A small cooler or insulated bag is useful for keeping drinks cold during port days, though some cruise lines restrict these items — check first.

Pack a light robe or cardigan for moving between your cabin and the pool or dining areas. Bring a small umbrella or rain jacket — even sunny cruises can have sudden showers, and ports often have unexpected weather. A pair of compression socks helps with circulation during long days of walking and sitting.

Include a small notebook and pen for jotting down port recommendations, restaurant reservations, or excursion details. Bring any books, e-readers, or downloaded entertainment you want — ship Wi-Fi is often too slow for streaming. A small sewing kit with thread in your clothing colors helps with quick repairs.

Consider packing a night light or small lamp if you're sensitive to darkness. Bring any special snacks you enjoy — the ship has food constantly available, but if you have specific dietary preferences or restrictions, packing backup snacks gives you peace of mind.

What not to pack and how to handle luggage

Do not pack prohibited items. Most cruise lines ban candles, incense, irons, hot plates, extension cords with outlets, surge protectors with outlets, weapons, and alcohol purchased outside the ship. Some lines restrict certain types of batteries, drones, and hoverboards. Check your specific cruise line's website — the rules vary.

Pack luggage that fits in your cabin. Cruise cabins are small — even suites have limited closet and storage space. One large suitcase and one carry-on per person is standard. If you're flying to the port, your airline's baggage allowance applies to your flight, not the cruise itself. Most cruise lines do not charge for luggage, but they may charge for excess bags.

Leave room in your luggage for purchases and souvenirs. Many people pack their suitcase completely full and then have nowhere to put items they buy at ports. Pack about 20 percent less than you think you need, or plan to check an additional bag on your return flight.

Label your luggage with your name, address, and phone number inside and out. If luggage is lost during your flight to the port, the cruise line will hold the ship for a reasonable time, but having clear identification helps it reach you faster.

Frequently Asked Questions

Can I bring my own alcohol on a cruise?

Most cruise lines prohibit bringing alcohol purchased outside the ship into your cabin or onto the ship itself. Some lines allow wine or beer in carry-on luggage during embarkation day only. Check your cruise line's specific policy — violations can result in the alcohol being confiscated or additional charges to your onboard account.

What if I forget something important?

Most cruise ships have small shops that sell basic clothing, toiletries, and sundries at higher prices than you would pay on land. If you forget something critical like medication, the ship's doctor can help, and some items can be shipped to your next port. Contact the cruise line's guest services as soon as you realize something is missing.

Do I need to pack formal shoes if I don't plan to dress up?

No. Casual dining is available every night, and you can eat there instead of formal dining. However, if you want the option to attend a formal dinner, bring at least one pair of dress shoes. Many people pack one nicer outfit and shoes just in case they change their mind.

Should I pack a power strip or extension cord?

Most cruise lines ban power strips and extension cords with outlets for safety reasons. Modern cabins have USB ports and at least one electrical outlet, which is usually enough for a phone charger and hair dryer. If you need more outlets, ask your cabin steward — they may have a solution that complies with ship rules.

What should I pack for a formal night if I don't own formal clothing?

You do not have to attend formal dinners. Casual dining is always available, and many people skip formal nights entirely. If you want to attend but don't own formal clothing, pack your nicest casual outfit — dress pants or a nice skirt with a blouse works for smart-casual dress codes, and many ships accept this for formal nights as well.
