The documents and IDs you cannot board without

Your passport is the single item that will stop you from boarding if it is missing or expired. Even if your cruise departs from a U.S. port and visits only U.S. ports, cruise lines require a valid passport for all passengers. Check the expiration date now—many cruise lines want at least six months of validity remaining, though some accept passports valid through your return date. If you do not have a passport or yours is expired, explore at your local passport acceptance facility (usually a post office, courthouse, or library) at least eight weeks before your departure.

Beyond your passport, bring a government-issued photo ID—a driver's license works—and your cruise documents. Your cruise line will email you a booking confirmation with your reservation number and passenger names. Print this or save it on your phone. Some cruise lines now use digital check-in through their app, but having the confirmation number written down is a backup that takes seconds and has saved countless passengers from delays at the port.

If you are traveling with children, bring their birth certificates even if they have passports. Cruise lines sometimes ask for proof of custody or relationship, especially if a child is traveling with someone other than both parents. A certified copy of the birth certificate settles the question when ready and costs nothing if you already have one at home.

Key Takeaways

  • Your passport must be valid for the entire duration of your cruise and is required even for cruises that visit only U.S. ports.
  • Pack medications in their original labeled bottles, bring a copy of prescriptions, and carry them in your carry-on bag, not checked luggage.
  • Bring copies of your insurance cards (health, travel, and home) and store them separately from the originals in case your wallet is lost.
  • A power adapter or converter is essential if your cruise visits ports outside North America, and USB charging ports are often limited in cabins.
  • Seasickness medication, sunscreen, and basic first-aid items are cheaper to bring from home than to buy onboard at cruise ship prices.

Medications and medical information you need to carry

Pack all prescription medications in their original labeled bottles with your name, the medication name, dosage, and pharmacy information clearly printed. Cruise lines and port authorities will inspect medications, and a bottle labeled only "pills" can create delays or confiscation. Bring enough medication for the entire cruise plus a few extra days in case of delays. If you run out mid-cruise, the ship's medical center can sometimes refill prescriptions, but the cost is high and availability is not may provide.

Carry medications in your carry-on bag or personal item, never in checked luggage. If your luggage is delayed or lost, you still have access to what you need. Bring a copy of each prescription or a letter from your doctor listing your medications and dosages—this helps if you lose your medication or need a refill at a port.

If you have a medical condition, wear a medical alert bracelet or carry a card listing your condition, medications, and emergency contact. The ship's medical staff will have this information if you become ill, and it can be the difference between appropriate treatment and a costly misdiagnosis. Bring a list of any allergies as well, especially food allergies if you plan to eat at specialty restaurants or request dietary accommodations.

Insurance documents and copies of important papers

Bring your health insurance card and a copy of your travel insurance policy if you purchased one. Travel insurance covers trip cancellation, medical emergencies, and evacuation—costs vary widely, but a policy typically runs $100 to $300 for a week-long cruise depending on your age and the cruise cost. Keep the original card in your wallet and a copy in a separate location, such as your phone or a second bag. If your wallet is lost, you still have proof of coverage.

Make a photocopy of your passport's information page and store it separately from your passport. If your passport is lost or stolen at a port, a copy speeds up replacement through the nearest U.S. embassy or consulate. Similarly, copy the front and back of your driver's license and any credit cards you plan to bring. Store these copies in your cabin safe or in a separate bag from the originals.

If you own a home, bring a copy of your homeowner's insurance policy and the agent's contact information. If a pipe bursts or a tree falls while you are away, you will want to file a claim quickly, and having the policy number and agent phone number accessible means you can call from the ship or a port and start the process when ready.

Toiletries and medications you should bring from home

Cruise ships sell toiletries and over-the-counter medications at prices two to four times higher than drugstore prices. Sunscreen, seasickness medication, pain relievers, antacids, and allergy medication are all cheaper to pack than to buy onboard. Bring full-size bottles of shampoo, conditioner, and body wash if you have preferences—cruise cabins provide basic soap and shampoo, but many people find the quality poor or the quantity insufficient for a week-long cruise.

Pack seasickness medication before you board, especially if you are prone to motion sickness or if your cruise includes rough-water routes. Dramamine, Bonine, or prescription scopolamine patches all work, but they work best if taken before you feel sick. Once nausea sets in, medication takes longer to work. Ginger supplements and acupressure wristbands are alternatives some passengers find effective.

Bring a basic first-aid kit: adhesive bandages, antibiotic ointment, pain reliever, antacid, and any personal medications. The ship has a medical center, but for minor issues like a blister or mild headache, having supplies in your cabin saves a trip and a wait. Include any prescription creams, ointments, or inhalers you use regularly—these are not always available at the ship's medical center.

Clothing and footwear for different ship activities and ports

Pack clothes for the ship's dress code, which varies by cruise line and itinerary. Most cruise lines have "formal" nights (usually one or two per week on longer cruises) where men wear suits or dress shirts and women wear dresses or dressy pants. "Smart casual" nights require collared shirts and dress pants or skirts. Daytime is casual—shorts, t-shirts, and sundresses are standard. Check your cruise line's website for the specific dress code for your sailing.

Bring comfortable walking shoes for ports. You will spend hours on your feet exploring towns, beaches, and excursions. Pack one pair of broken-in walking shoes and one pair of sandals or slip-ons for casual wear. Avoid new shoes on the cruise—blisters in port are miserable and limit what you can do. Include one pair of dressier shoes for formal nights.

Pack a light jacket or sweater even if your cruise is to warm destinations. Dining rooms and theaters are heavily air-conditioned, and evening breezes on deck can be cool. A thin layer you can remove is more practical than being cold during dinner. If your cruise visits northern ports or sails in winter, pack warmer outerwear and layers.

Electronics and charging solutions for your cabin

Bring your phone charger and a power adapter if your cruise visits ports outside North America. Most cruise cabins have one or two electrical outlets, often positioned inconveniently behind the bed or desk. A power strip with USB ports lets you charge multiple devices at once—your phone, tablet, camera, and any other electronics. Check your cruise line's policy on power strips; most allow them, but a few prohibit them for safety reasons.

A portable battery pack (power bank) is useful for days at ports when you are away from your cabin for eight or ten hours. A 20,000 mAh battery pack costs $20 to $40 and will fully charge a smartphone three to four times. This is cheaper than buying drinks and snacks at port cafes while you wait for your phone to charge.

Bring a waterproof phone case or bag if you plan to use your phone at the beach or pool. Salt water and chlorine damage phones quickly, and replacement or repair onboard is expensive. A waterproof case costs $10 to $30 and protects your phone and lets you take photos in the water.

Money, payment methods, and what costs extra onboard

Most cruise lines use a onboard account system where charges go to your cabin and you pay at the end of the cruise. Link a credit card to your account before boarding so you do not have to carry large amounts of cash. Bring a credit card and a debit card as backups in case one is declined or lost. Notify your bank and credit card companies of your travel dates so they do not flag charges as fraudulent.

Bring some cash in the currency of your first port. Tipping at ports, small purchases, and emergencies are easier to handle with local currency. Exchange rates at the ship are typically poor, so exchange money before boarding or at an ATM in your first port. Most ports have ATMs near the cruise terminal.

Understand what is included in your cruise fare and what costs extra. Most cruise lines include meals in the main dining room and buffet, but specialty restaurants, alcohol (except on all-inclusive packages), beverage packages, spa services, and excursions all cost extra. Internet is usually not included and can cost $15 to $30 per day. Gratuities (tips for housekeeping and dining staff) are typically $15 to $16 per person per day and are automatically added to your account unless you opt out.

Frequently Asked Questions

Do I need a passport if my cruise starts and ends in the same U.S. port?

Yes. Even if your cruise visits only U.S. ports or no ports at all, cruise lines require a valid passport for all passengers. A few older cruises to nowhere or closed-loop Caribbean cruises may accept a Real ID driver's license or state ID, but policies change and a passport is the safest choice. Check with your specific cruise line, but assume you need a passport.

Can I bring my own alcohol onboard?

Most cruise lines prohibit passengers from bringing alcohol onboard. Wine and beer brought in luggage are confiscated at check-in. Some cruise lines allow one bottle of wine or champagne per cabin if purchased at the port and brought onboard that day, but policies vary. Check your cruise line's website before packing any alcohol.

What should I do if I forget something important?

The ship's purser's office can help you contact family or friends to ship items to your next port, though this is slow and expensive. For medications, the ship's medical center may be able to help or provide temporary supplies. For documents like insurance cards, photos stored on your phone or email are usually sufficient proof. Most forgotten items can be worked around; focus on packing medications, passport, and payment methods.

How much luggage can I bring?

Cruise lines typically allow two checked bags per person at no extra charge, plus a carry-on and personal item. Bag size limits vary—most allow bags up to 50 pounds and 22 by 14 by 9 inches. Check your cruise line's baggage policy on their website. Oversized or extra bags usually incur fees of $15 to $50 per bag.

Should I buy travel insurance?

Travel insurance covers trip cancellation, medical emergencies, and evacuation. If you are traveling far from home, have a medical condition, or booked an expensive cruise, insurance is worth considering. If you are taking a short, inexpensive cruise and are in good health, the cost may not be worth it. Review what your health insurance and credit card already cover before purchasing a separate policy.
