Cruise packing is the opposite problem from every other kind of travel. Airlines punish you for bringing too much; cruise lines mostly do not care how much you bring aboard. There is no weight limit at the terminal, no gate agent with a sizer.
The constraint moves somewhere else entirely: your cabin. A standard interior cabin is around 15 square metres with a wardrobe the size of a hall cupboard, and you will be living in it for a week. And unlike a hotel, a cruise ship has a list of items security will physically take off you at check-in.
This guide covers what to pack for a 7-day cruise, what the ship will confiscate, and the one bag that matters more than all your luggage combined.
1. The Short Answer: A 7-Day Cruise
| Category | What to bring |
|---|---|
| Daywear | 5-6 casual outfits, swimwear x2, cover-up |
| Evening | 4-5 smart casual outfits, 1-2 formal night outfits |
| Shoes | Trainers, sandals, one dressy pair, water shoes for excursions |
| Embarkation bag | Swimwear, meds, documents, sun cream, change of clothes |
| Cabin | Magnetic hooks, over-door organiser, nightlight |
| Health | Motion sickness remedy, prescription meds, plasters |
| Ports | Day pack, small notes in local currency, reef-safe sun cream |
The single most important item is not on that list — it is the day bag you carry on at embarkation. More on that in section 3.
2. What Cruise Lines Confiscate
This section saves more grief than anything else here. Cruise security screens every bag at the terminal, and the following are taken off you:
- Clothing irons and steamers. Banned on essentially every line, and by a wide margin the most confiscated item. They are a fire risk in a cabin. Ships have laundry services and often self-service launderettes with irons in a supervised room.
- Candles and anything with an open flame.
- Extension cords with surge protection. Surge protectors interfere with the ship's electrical system. Some lines permit a plain, non-surge extension lead; others refuse all of them. Check your line's published policy rather than guessing.
- Hot plates, kettles, and heating elements.
- Drones, on most lines, or held by security until the end of the sailing.
Alcohol is its own category. Most mainstream lines allow one bottle of wine or champagne per adult at embarkation and confiscate spirits, which are returned at the end of the cruise. Policies vary enough that this is worth checking specifically.
3. The Embarkation Day Bag
This is the thing experienced cruisers get right and first-timers learn the hard way.
When you drop your luggage at the terminal, you will not see it again for hours. Bags are sorted, screened, and delivered to cabins throughout the afternoon and sometimes into the evening. Meanwhile the ship sails, the pool opens, and the first dinner service starts.
Pack a small day bag you carry on yourself, containing:
- Swimwear and a cover-up — the pool is empty and glorious on embarkation afternoon
- All prescription medication, in original packaging
- Travel documents, passport, boarding pass, credit card
- Sun cream and sunglasses
- A change of clothes
- Phone charger and power bank
- Anything valuable or fragile
Everything else can sit in a checked bag. If you take one thing from this guide, take this.
4. Evening Wear and Formal Nights
Cruise dress codes have relaxed considerably, and most mainstream lines — Royal Caribbean, Carnival, Norwegian, MSC — now describe their dressy evenings as smart or elegant casual rather than black tie. Premium and luxury lines such as Cunard hold a stricter line.
A 7-day sailing typically has one or two formal evenings. That means:
- One dark suit, or a jacket with smart trousers
- Or one cocktail dress, or dressy separates
- One pair of dressy shoes
That is genuinely all. Packing a tuxedo and three gowns for a week-long mainstream cruise is the classic overpack, and it eats the small wardrobe you have.
Regular evenings are smart casual — collared shirts, dresses, nice trousers. Most ships ask you not to wear swimwear or vests in main dining rooms, and that is the extent of it.
Because evening wear repeats and daywear does not, the capsule approach works especially well on a ship. Our travel capsule wardrobe guide covers building a coordinated palette where nearly everything pairs with everything else.
5. The Cabin Problem
Cruise cabins are small, and storage is the scarce resource. A few cheap items make a disproportionate difference:
- Magnetic hooks. Cabin walls and ceilings are steel. Magnetic hooks turn blank wall into hanging space for hats, bags, lanyards, and wet swimwear. This is the single best-value cruise item.
- Over-the-door shoe organiser. Hangs on the bathroom door and holds toiletries, sun cream, sunglasses, and small items that would otherwise cover every flat surface.
- A small nightlight. Interior cabins are absolutely dark — no windows, no ambient light at all. Getting to the bathroom at 3 a.m. is genuinely disorienting without one.
- Collapsible laundry bag to keep worn clothes off the floor.
- Lanyard with a card holder for your keycard, which you need constantly for your cabin, your onboard account, and getting on and off the ship in port.
Power is limited. Older ships have as few as two sockets in a cabin, often a mix of US 110V and European 220V, sometimes with a couple of USB ports. A plain multi-plug adapter without surge protection helps if your line permits one.
6. Shore Excursions
Port days are a different trip from ship days, and they need their own small kit:
- A day pack, ideally one that packs flat in your luggage
- Small denominations of local currency — many port towns are cash-only
- Reef-safe sun cream if you are snorkelling; several Caribbean and Pacific destinations restrict sunscreens containing oxybenzone
- Water shoes for rocky beaches and wet landings
- A refillable water bottle, filled on the ship before you go
- A photo of your passport on your phone, plus the ship's contact card
- A light rain layer in tropical regions, where afternoon showers are routine
Watch the all-aboard time, which is typically 30-60 minutes before departure and is set in ship's time — which does not always match local time in port. Independent excursions carry the risk of being left behind; ship-operated ones do not.
7. What Changes by Region
Caribbean. Hot, humid, sunny. Heavy on swimwear, sun protection, and light fabrics. Afternoon rain showers are brief. This overlaps closely with general tropical packing — our beach vacation packing list covers the sun and sand side in more depth.
Mediterranean. Warm days, cooler evenings, and a great deal of walking on stone and cobbles in port. Bring proper walking shoes and one layer for evenings on deck. Many Mediterranean itineraries include churches and cathedrals with shoulder-and-knee dress codes, so pack a light scarf.
Alaska and Northern Europe. Genuinely cold on deck even in summer, especially during glacier viewing. Layers, a waterproof outer shell, a warm hat, and gloves. Binoculars are worth the space for wildlife.
Repositioning and transatlantic. Many consecutive sea days, variable weather, and more formal evenings than a typical week-long sailing. Pack more books and more evening wear than you think.
8. Health and Practicalities
- Motion sickness. Even on large modern ships with stabilisers, open ocean crossings move. Bring your preferred remedy — tablets, patches, or bands — because onboard shops charge a premium. A midship cabin on a lower deck moves least.
- Prescription medication in original labelled packaging, with enough for the full trip plus several spare days in case of an itinerary change.
- Basic first aid. Onboard medical centres are excellent but charge private rates for everything, including paracetamol.
- Hand sanitiser. Ships are strict about it for good reason — norovirus spreads fast in a closed environment.
- Laundry. Some ships have self-service launderettes, some have none and offer bag specials mid-cruise. If yours has neither, pack accordingly.
9. What Not to Pack
- An iron or steamer. It will be confiscated. This bears repeating because it is that common.
- Beach towels. Every ship provides them for the pool and for going ashore.
- A hairdryer. Cabins have one, and while it is usually weak, it is adequate.
- Formal wear for every night. One or two dressy outfits covers a week.
- Large bottles of toiletries. No airline liquid limit applies to a bag you drop at the cruise terminal, but your cabin bathroom shelf is tiny.
- Snorkel gear, unless you are particular about fit. Excursions include it.
10. Building the List with PackPilot
A cruise is a good example of a trip that is really several trips stacked together: embarkation day, sea days, formal evenings, and port days each need different things, and forgetting one category is what ruins the first afternoon.
In PackPilot, set the trip type to cruise, enter your sailing length, and add the ports on your itinerary. Zippy builds a categorised list that separates those contexts instead of producing one flat list. Bag assignment is genuinely useful here — you can keep the embarkation day bag as its own bag and see at a glance whether your swimwear and medication are in it rather than in a checked case somewhere in the terminal.
Everything works offline, which matters more on a cruise than almost anywhere else. Ship wifi is expensive and slow, and mobile data at sea is either unavailable or charged at maritime roaming rates.

Frequently Asked Questions
Clothing irons and steamers are prohibited on virtually every cruise line and are the most commonly confiscated item at the terminal — they are a fire risk. Also banned: candles, extension cords with surge protection, hot plates, and drones on most lines. Power strips without surge protection are allowed by some lines and refused by others, so check your specific line before packing one.
Most mainstream lines now describe it as smart or elegant casual rather than black tie. A dark suit or a jacket with trousers works for men, and a cocktail dress or dressy separates for women. A 7-day sailing typically has one or two of these evenings, so one outfit is enough. Luxury and premium lines are stricter, so check your line before assuming.
Your checked bags are delivered to your cabin hours after you board, sometimes not until evening. Keep swimwear, medication, a change of clothes, sun cream, travel documents, and anything valuable in a small day bag you carry on. Passengers who pack swimwear in a checked bag routinely miss the first afternoon at the pool.
Cruise lines are far more generous than airlines — most have no strict weight or piece limit for luggage brought aboard at the terminal. The real constraint is your cabin, which is small and has limited storage. Your flight to the port is usually the binding limit, not the ship.
Onboard spending goes on your keycard account, so cash is not needed on the ship. You do want small notes for shore excursions, local markets, taxis, and tipping guides in port. Many ports outside major cities are cash-only.
Yes. Set the trip type to cruise, add your sailing length and the ports you are visiting, and Zippy builds a list covering formal nights, embarkation day, pool days, and shore excursions. Bag assignment is useful here because it separates your embarkation day bag from checked luggage that arrives later.
