Pack These Items Before You Board
The items that matter most on a cruise are the ones you'll reach for every single day: your passport or state ID, medications in their original bottles, a basic toiletry kit, and comfortable walking shoes. Cruise lines provide towels, soap, and shampoo in your cabin, so you do not need to pack full-size bottles. What you do need is anything prescribed to you by name, because the ship's medical staff cannot refill prescriptions from home.
Bring copies of important documents—your cruise ticket, travel insurance information, and emergency contact numbers—stored separately from the originals. A small day bag works better than a large suitcase for moving around the ship and going ashore. Pack one outfit for formal dining (if your cruise includes formal nights), one for casual dining, and the rest in layers you can mix and match.
Key Takeaways
- Your passport or state ID is non-negotiable; the ship will not leave port without it, and you cannot board without it.
- Medications must be in their original labeled bottles with your name on them, because cruise ship doctors cannot refill prescriptions.
- Comfortable walking shoes are essential—you will spend hours on your feet exploring ports and the ship itself.
- Sunscreen, a reusable water bottle, and motion sickness medication (if you are prone to seasickness) will make your days more comfortable than any luxury item.
- Leave behind items the cruise line forbids: candles, irons, surge protectors with outlets, and anything with a heating element.
Documents and Money You Cannot Leave Behind
Your passport or state ID is the single item you cannot replace once you are at sea. Cruise lines require it to board, to clear customs at each port, and to re-board after you go ashore. If you lose it during the cruise, the ship's purser can help you contact your embassy, but you will miss port days while you wait for a replacement. Keep it in your cabin safe, not in your pocket.
Bring a credit card and a small amount of cash in the local currency of your first port. Most cruise ships run on a cashless system—you charge everything to your cabin account, which you settle when you leave—but some ports and small vendors ashore accept only cash. A second credit card, kept separate from the first, protects you if one is lost or declined.
Clothing That Works for Multiple Days
Pack clothes that layer and repeat. Five to seven shirts, two pairs of pants or shorts, and one pair of jeans cover most cruises because you can wear the same item twice before laundry day. Bring one outfit for formal or elegant dining (a dress, suit, or nice pants and a button-up shirt), one for casual dining, and the rest in neutral colors that match each other.
Comfortable walking shoes are not optional—you will spend four to six hours a day on your feet exploring ports and walking the ship's corridors and decks. Pack a second pair in case one gets wet. Bring a light sweater or fleece because ship cabins and dining rooms are heavily air-conditioned, and upper decks can be cool at night. Sandals or slip-ons are useful for moving quickly between your cabin and the pool.
Toiletries and Medications You Must Bring
Cruise lines provide basic soap, shampoo, and towels, so you do not need full-size bottles. Bring a small toiletry bag with deodorant, toothbrush, toothpaste, any face products you use daily, and feminine hygiene products if you need them. The ship's small cabin bathroom will not have space for more than this.
All medications must be in their original labeled bottles with your name printed on them. The ship's doctor cannot refill prescriptions or provide medications without this documentation. If you take medication multiple times a day, bring enough for the full cruise plus three extra days in case of delays. Pack medications in your carry-on bag, not in checked luggage, so they are with you if your suitcase is delayed.
Items That Make Days More Comfortable
Sunscreen is the one item most people regret not bringing enough of. Ship stores sell it at high prices, and you will use more than you expect because you are on the water where sun reflects off the surface. Bring a broad-spectrum SPF 30 or higher in a size you can refill at ports. A reusable water bottle keeps you hydrated on deck and ashore without buying bottled water at each port.
Motion sickness medication—whether ginger supplements, acupressure wristbands, or prescription patches—matters only if you get seasick, but if you do, you will wish you had it. Seasickness is worst on the first day and in rough water, and it ruins port days because you will not want to leave your cabin. A small first-aid kit with adhesive bandages, pain relievers, and antacids covers the minor complaints that happen on any trip.
Bring a phone charger and a universal power adapter if you are traveling internationally. Cabin outlets are often far from the bed, so a longer cable or a small power strip (check your cruise line's rules—some forbid them) makes charging easier. A small flashlight or headlamp is useful for reading in bed without waking a cabin mate.
Items Cruise Lines Forbid
Cruise lines prohibit items with heating elements because of fire risk: irons, hair dryers (though cabins usually have one), candles, and hot plates. They also forbid surge protectors with outlets, extension cords longer than six feet, and anything that plugs into a wall outlet and has a switch. Weapons of any kind, including pocket knives and corkscrews, are forbidden. Alcohol brought aboard is confiscated at check-in, though you can purchase it on the ship.
Do not pack aerosol cans, including spray sunscreen and spray deodorant, because they are restricted in cargo holds. Bring stick or roll-on versions instead. Glass bottles are forbidden on deck because of breakage risk, so pack sunscreen and toiletries in plastic or metal containers. Check your specific cruise line's website for their full prohibited items list, because rules vary slightly between lines.
What to Leave at Home
Expensive jewelry, watches, and electronics beyond a phone and camera are not worth the risk. Cruise ship cabins have safes, but theft does happen, and replacing items at sea is impossible. Leave behind anything you would be upset to lose.
Do not overpack "just in case" items. A seven-day cruise does not require seven different outfits because laundry service is available (though it costs extra), and you will wear the same comfortable clothes repeatedly. A carry-on suitcase and a small day bag are enough for most cruises. Overpacking makes your cabin feel cramped and makes moving through ports exhausting.
Frequently Asked Questions
Do I really need to bring my own sunscreen?
Yes. Ship stores charge two to three times the price of drugstore sunscreen, and you will use more than you expect because sun reflects off the water. Bring at least SPF 30 broad-spectrum in a size you can refill at ports if your cruise is longer than a week.
Can I bring my own hair dryer?
Most cruise cabins have a hair dryer mounted on the wall or in a drawer, so you do not need to bring one. If yours is missing, the front desk will provide one. Bringing your own takes up luggage space and risks damage from the ship's electrical system.
What if I forget something important?
The ship's small store sells basics like toothpaste, deodorant, and over-the-counter pain relievers at high prices. For medications, the ship's doctor can sometimes help, but it is not may provide. Ports often have pharmacies and drugstores where you can replace forgotten items at normal prices.
Should I pack formal clothing if I am not sure about dress codes?
Check your cruise line's website for their specific dress code policy—some lines have formal nights, others do not. If your cruise includes formal or elegant nights, pack one outfit that fits the code. If you are unsure what you own qualifies, a nice pair of pants or a dress with a button-up shirt or blazer works for most lines.
Can I bring a power strip to charge multiple devices?
Many cruise lines forbid power strips with outlets because of fire risk. Check your specific line's rules before packing. A longer phone charger cable or a small power bank (battery pack) is a safer way to charge multiple devices without violating rules.
