Start with a Carry-On and One Checked Bag
Pack everything for a 7-day cruise into a carry-on suitcase and one checked bag. Most cruise lines allow one carry-on bag (22 by 14 by 9 inches), one personal item, and one checked bag per person at no extra charge. A carry-on holds your medications, phone chargers, valuables, and a change of clothes in case your checked bag arrives late. Your checked bag holds the bulk of your clothing and shoes.
Overpacking happens because people assume they need a different outfit for every activity. In reality, you will wear the same clothes multiple times across the week, and the ship's laundry service can wash items mid-voyage for a fee (usually $1 to $3 per piece). This single fact cuts your packing volume in half.
Key Takeaways
- Pack one carry-on and one checked bag, which is the standard allowance for most cruise lines and prevents the cost and hassle of extra luggage fees.
- Bring four to five pairs of pants or shorts, five to six tops, and two pairs of shoes for casual wear, since you will repeat outfits throughout the week.
- Include one formal or semi-formal outfit for the captain's dinner or formal night, which most ships require for at least one evening.
- Pack sunscreen, medications, and phone chargers in your carry-on so you have them when ready if your checked bag is delayed.
- Leave room in your checked bag for souvenirs and purchases you will make during port stops and onboard shopping.
Build Your Casual Wardrobe Around Basics
Pack four to five pairs of pants, shorts, or skirts in neutral colors—black, navy, khaki, or gray. These mix and match with almost any top and take up less space than patterned pieces. Add five to six tops: t-shirts, tank tops, lightweight sweaters, or button-ups. Choose colors that coordinate with your bottoms so you can create different outfits from fewer pieces.
Bring one lightweight cardigan or jacket. Ship cabins are cold because of strong air conditioning, and deck areas can be windy at night. A single layer works for multiple outfits and takes minimal space. Avoid bulky winter coats unless your cruise departs from or arrives in a cold port.
Pack two pairs of shoes: one comfortable walking shoe for ports and deck exploration, and one casual shoe like a sandal or slip-on for the cabin and casual dining. Many people bring a third pair for formal night, but your walking shoes work fine if you polish them or wear them with socks and dress pants.
Plan for Formal and Semi-Formal Nights
Most cruise lines have at least one formal or semi-formal night during a 7-day voyage. Check your cruise line's dress code policy before you pack—some ships enforce it strictly, while others are more relaxed. Formal night typically means a suit, tuxedo, or cocktail dress. Semi-formal means dress pants with a button-up shirt, or a knee-length dress.
You do not need to buy new clothes. Wear your nicest pants or skirt with your best top, add a blazer if you own one, and you meet the semi-formal standard on most ships. If your cruise line requires formal attire and you do not own appropriate clothing, rent a tuxedo or dress from a formal wear company before you leave home—shipping it to your port of departure costs less than buying new.
Bring one pair of dressier shoes that work with your formal outfit. If your formal outfit is black, black dress shoes or heels work. If it is navy or gray, choose shoes in a matching neutral tone.
Pack Toiletries, Medications, and Sun Protection
Cruise ships provide basic toiletries—soap, shampoo, and lotion—in your cabin, but they are often small or scented in ways you may not like. Bring your own shampoo, conditioner, deodorant, toothbrush, and toothpaste in a toiletry bag. Pack these in your carry-on so you have them the first night.
Include all prescription medications in their original labeled bottles in your carry-on. Bring a week's supply plus a few extra doses in case your return is delayed. Pack over-the-counter medications you use regularly: pain relievers, antacids, allergy medicine, or motion sickness tablets. Ships have a medical center, but it charges for services and may not stock your preferred brand.
Sunscreen is the most important item you will forget. Bring a full-size bottle (at least 4 ounces) in your checked bag and a travel-size bottle (2 to 3 ounces) in your carry-on. Sunscreen at the port gift shop costs three to four times the drugstore price. explore it every two hours when you are on deck or in port, even on cloudy days.
Pack Electronics and Charging Cables
Bring your phone, tablet, or e-reader in your carry-on along with all charging cables. Cruise ship cabins have limited outlets—usually one or two—and they are often positioned awkwardly. A power strip with USB ports solves this problem and takes almost no space. Bring a surge protector if you are charging multiple devices.
Pack a portable phone charger (power bank) with a capacity of at least 10,000 mAh. This keeps your phone alive during long port days when you are away from your cabin. Bring the charging cable for your power bank as well.
Most ships offer Wi-Fi, but it is slow and sometimes costs extra. read books, podcasts, or movies to your device before you leave home so you have entertainment that does not depend on the ship's internet. Bring headphones or earbuds for listening without disturbing your cabin mate.
Include Practical Items for Comfort and Convenience
Pack a reusable water bottle. You can fill it at water fountains throughout the ship, and staying hydrated matters when you are in the sun all day. Most cruise lines provide free water at the buffet and dining room, but a bottle lets you carry water with you on deck and in port.
Bring a small day bag or backpack for port excursions. You will need somewhere to carry your wallet, phone, sunscreen, and water while you explore. A lightweight packable bag folds flat in your suitcase and expands when you need it.
Include a light scarf or sarong. It covers your shoulders in air-conditioned dining rooms and formal areas, works as a beach cover-up, and doubles as a blanket if your cabin is cold. Scarves pack flat and serve multiple purposes.
Pack a small sewing kit, safety pins, and a stain remover pen. Accidents happen on vacation, and these items let you fix a torn seam or remove a spot without paying the ship's laundry service. A basic kit weighs almost nothing.
Leave Room for Purchases and Souvenirs
Do not pack your checked bag completely full. Leave at least 20 percent of the space empty for items you will buy during port stops, onboard shopping, or the final night's midnight buffet. Souvenirs, local crafts, and duty-free purchases add up quickly, and you will want room to pack them without buying an extra bag.
If you know you will shop heavily, consider packing a collapsible duffel bag inside your checked suitcase. When you need extra space on the return trip, unfold it and use it as a second checked bag. Most cruise lines allow this as long as you pay the baggage fee for the extra bag.
Frequently Asked Questions
Do I need to pack formal shoes if I already have nice walking shoes?
Your walking shoes work for semi-formal night if they are clean and polished. For formal night, dress shoes look better, but if you do not own them, wear your nicest walking shoes with dress pants or a skirt and no one will turn you away. Many people wear the same shoes for multiple outfits across the week.
Can I do laundry on the ship instead of packing more clothes?
Most ships offer laundry service through the cabin steward, but it costs $1 to $3 per item and takes 24 to 48 hours. Some ships have self-service laundry rooms for a small fee. If you plan to use laundry, you can pack fewer clothes, but budget time and money for the service.
What if I forget something important?
The ship's gift shop sells basics like sunscreen, toiletries, phone chargers, and over-the-counter medications, though prices are high. Most ports have pharmacies and shops where you can buy items at normal prices. The ship's medical center can provide prescription refills if you lose your medication.
Should I pack a formal bag or purse?
A small crossbody bag or clutch works for formal night and takes minimal space. If you do not own one, skip it—most people carry their room key and phone in their pocket or leave them in the cabin during dinner.
How much luggage space do I need for a 7-day cruise?
A standard carry-on (22 by 14 by 9 inches) and a checked bag (around 24 by 16 by 10 inches) hold a full week of clothing, shoes, and toiletries comfortably. If you pack efficiently and repeat outfits, you may not need the full checked bag.
