Pack these items before you board

A cruise requires less luggage than a land trip, but you need specific things or you'll spend money replacing them onboard. Bring your passport or passport card (required for any cruise that leaves U.S. waters), travel documents from your cruise line, medications in their original bottles, and copies of your insurance cards. Pack a small day bag for the first day — your checked luggage may not reach your cabin until evening.

Bring a reusable water bottle (empty at security, fill it onboard), sunscreen rated SPF 30 or higher, and a light rain jacket. Most cruise lines prohibit candles, irons, and hot plates in cabins, so don't pack those. Check your cruise line's website for their specific prohibited items list before you pack — it varies by line and ship.

Key Takeaways

  • Your passport or passport card is required for any cruise leaving U.S. waters, and you cannot board without it.
  • Pack medications in their original labeled bottles and bring copies of prescriptions in case you need refills onboard.
  • Bring a small day bag with essentials for your first evening, since checked luggage often arrives hours after you board.
  • Sunscreen, a reusable water bottle, and a light jacket are the most useful items most people forget.
  • Check your specific cruise line's prohibited items list — rules differ between lines and some items you might expect to bring are banned.

Documents and identification you cannot board without

Your passport or passport card is required for any cruise that departs from a U.S. port and visits another country. If your cruise stays within U.S. waters only (for example, some Caribbean itineraries that visit only U.S. territories), you may be able to use an Enhanced Driver's License or a Trusted Traveler card like NEXUS, but your cruise line will tell you which documents they accept. Check your documents now — passport cards expire just like regular passports, and processing a replacement takes weeks.

Bring your cruise line's travel documents, which they send by email or mail before your departure date. These include your booking confirmation, your cabin assignment, and your onboard account setup. Print them or save them to your phone. Bring copies of your insurance cards (health, travel, and home if you're concerned about your house while you're gone), your driver's license, and one credit card you don't plan to use for onboard charges — you'll need it to open your onboard account, and the cruise line will place a hold on it.

Medications and health items that are hard to replace onboard

Pack all prescription medications in their original labeled bottles with your name on them. The ship's medical center can refill some medications, but they charge a consultation fee (typically $100 to $200) plus the cost of the medication, and they may not stock what you need. Bring a copy of each prescription or a note from your doctor listing the medication name and dose — if you lose your bottle, the ship's doctor can use this to verify what you take.

Pack over-the-counter medications you use regularly: pain relievers, antacids, allergy medicine, and motion sickness medication if you're prone to seasickness. Bring enough for your entire trip plus a few extra days. The ship's shop sells these items, but at resort prices — expect to pay two to three times what you'd pay at home. If you wear glasses or contacts, pack a spare pair and bring your prescription. The ship may have an optometrist, but getting an appointment takes time you don't have on a short cruise.

Clothing and footwear for different ship areas

Pack one outfit nicer than casual for formal or semi-formal dining nights — most cruise lines have at least one or two of these per week. Men need dress pants and a button-up shirt or blazer; women need a dress, skirt and blouse, or dressy pants. You don't need a tuxedo or evening gown unless you want one. Check your cruise line's website for their specific dress code, which varies by line and ship.

Bring comfortable walking shoes you've already worn — breaking in new shoes on a cruise is miserable. Pack sandals or slip-ons for the pool deck and casual dining. Bring one pair of dressier shoes for formal nights. Most people overpack clothes; you'll wear the same few outfits repeatedly, and the ship has laundry service (paid) or self-service laundromats (free or low-cost). Pack seven days of underwear and socks, then plan to do laundry or reuse items.

Toiletries and personal care items

Cruise ship cabins provide basic soap and shampoo, but most people prefer their own. Pack travel-size bottles of shampoo, conditioner, body wash, and lotion, or buy them onboard. Bring your toothbrush, toothpaste, deodorant, and any face products you use daily. Pack sunscreen — the ship's shop sells it at high prices, and you'll use more than you expect.

Bring a small first-aid kit: bandages, antibiotic ointment, pain relievers, and anti-diarrhea medication. Pack any feminine hygiene products you use; the ship may not stock your preferred brand. Bring your regular hair care items (styling products, hair ties, etc.) because the ship's shop carries limited options. A small sewing kit with a needle, thread, and a few buttons can fix a popped button or small tear without waiting for the ship's laundry service.

Electronics and chargers you'll actually use

Bring your phone charger and a portable battery pack — your phone will be your room key, your onboard account, and your way to check the daily activities schedule. Pack a charger for any other devices you bring (tablet, camera, hearing aids). Most modern cruise ships have USB outlets in cabins, but they're often in inconvenient spots, so a portable battery is useful.

Bring a universal power adapter only if you're visiting ports outside North America. Most Caribbean and Mexican ports use the same outlets as the U.S., so you won't need one. If you're bringing a laptop, bring its charger, but most people find they don't use it on a cruise. Leave your hair dryer at home — cruise cabins provide them, though they're often weak.

Items that save money or solve common problems

Bring a reusable water bottle and fill it at the ship's water fountains — bottled water onboard costs $2 to $4 per bottle. A light rain jacket or poncho takes up almost no space and saves you from buying one at a port gift shop for $30. Bring a small day bag or backpack for excursions and port days; the ship's gift shop sells these for $25 to $50.

Pack a small flashlight or headlamp if you're prone to getting up at night — cruise ship hallways are dimly lit. Bring a universal sink plug if you want to hand-wash delicate items. Pack a few plastic bags for wet swimsuits or dirty laundry. Bring a book, e-reader, or read shows to your phone for downtime — the ship's internet is slow and expensive, and you may want quiet time away from the crowds.

What not to pack because it's prohibited or pointless

Do not pack candles, incense, or any open flame item — cruise lines prohibit these for fire safety. Do not bring an iron, hot plate, or electric kettle. Do not pack weapons of any kind, including pocket knives or multi-tools. Do not bring large amounts of alcohol; most cruise lines allow one bottle of wine or champagne per person in your cabin, but prohibit hard liquor. Alcohol you bring onboard will be confiscated, though it's returned when you leave the ship.

Do not pack a full-size hair dryer, curling iron, or straightener — your cabin provides a hair dryer, and bringing your own takes up space. Do not pack dress shoes you haven't broken in. Do not bring expensive jewelry you can't afford to lose — theft happens, and the ship's safe is small. Do not pack a suitcase larger than your cruise line allows; most lines limit checked bags to 50 pounds and carry-ons to standard airline size.

Frequently Asked Questions

Can I bring my own food or snacks on a cruise?

Most cruise lines allow you to bring snacks like granola bars, crackers, and candy in your carry-on bag. They prohibit fresh fruit, vegetables, and meat. Check your specific cruise line's policy before you pack. Many people bring snacks because the ship's 24-hour buffet closes at certain times, and you may want something between meals.

Do I need to pack formal shoes if I don't like dressing up?

No. If your cruise line has formal or semi-formal nights and you don't want to attend those dinners, you can eat at the casual buffet or order room service instead. You don't have to dress up for any meal. If you do want to attend formal dinners, bring one pair of dressier shoes — they don't have to be formal, just nicer than sneakers.

What should I pack for ports if I'm doing excursions?

Wear comfortable walking shoes, bring sunscreen, and pack a light layer in case you're in air conditioning. Bring a small backpack or day bag, a reusable water bottle, and a camera if you want one. Wear clothes you don't mind getting wet or dirty. Most ports have shops where you can buy anything you forgot, though prices are high.

Is it worth buying travel insurance before I cruise?

Travel insurance covers trip cancellation, medical emergencies, and lost luggage. It's worth considering if you're paying a lot for your cruise, have health concerns, or are traveling during hurricane season. Your homeowner's or renter's insurance may cover some losses, so check your policy before buying additional coverage.

Can I bring a CPAP machine or other medical equipment?

Yes. Pack your CPAP, oxygen concentrator, or other medical equipment in your carry-on bag. Bring extra supplies and batteries. Notify your cruise line in advance that you're bringing medical equipment so they can help you if you have questions about power outlets or storage in your cabin.
