What to Pack for a Cruise

Cruise packing is its own genre. Unlike a hotel-based trip, you're packing for a small floating city with dress codes, formal nights, port-day excursions, and the inconvenient fact that any item you forgot is going to cost three times as much from the onboard shop or be unavailable entirely. The kit that handles a cruise well is more layered than people expect.

Start with the dress code reality. Most major cruise lines have at least two dress codes onboard: smart casual most nights, formal one or two nights per week. 'Formal' on a cruise means a suit and tie or a cocktail dress, not a tuxedo and gown — though tuxedos appear on some longer voyages. Pack accordingly. For men: a sport coat, two collared shirts, one tie, and dress shoes. For women: one cocktail dress, one nice top with a midi skirt or pants, and dress shoes. These pieces should compress into a quarter of your bag.

Daytime onboard wear is more casual than people imagine. Lightweight athleisure for the gym, swimwear plus a coverup for pool deck (most ships have multiple pools and waterslides for kids), shorts and t-shirts for general daytime use. Bring a lightweight cardigan or hoodie because cruise ship interiors are aggressively air-conditioned, sometimes uncomfortably so.

Port days drive the rest of the kit. If your itinerary includes Alaska, Norway, or Iceland, pack a real waterproof shell, warm layers, and waterproof shoes for shore excursions. If it's Caribbean or Mediterranean, the beach-plus-walking-shoes combo from any beach trip applies. If you're tendering (small boats from ship to shore on a few stops), waterproof shoes are non-negotiable on those days. A small lightweight backpack for shore excursions is worth its weight.

Cruise-specific items most people forget. A power strip without surge protection (cruise lines prohibit surge protectors but allow plain extension strips, and cabins have very few outlets). A magnetic hook (cabin walls are steel and magnetic hooks turn empty wall space into a rack for hats, lanyards, and bags). Refillable water bottles (most cruise lines allow them and tap water is free; bottled water is expensive). Motion sickness remedies even if you don't think you need them — Bonine, Sea-Bands, or prescription scopolamine patches if you're sensitive.

Toiletries and medications. Cruise cabin bathrooms are tiny. Pack toiletries in a hanging organizer that hooks over the door — it doubles your usable space. Bring more medication than you'll need; most ships have minimal pharmacies. If you wear contacts, bring a pair of glasses as backup; replacing contacts onboard is expensive or impossible. Sunscreen in larger quantities than you'd take for a hotel trip — ship pricing on sunscreen is brutal.

Documents matter more on cruises than other trips. Bring your passport (most cruise lines now require it even for closed-loop cruises that don't strictly need one), proof of vaccination if your line still requires it, your booking confirmation, and any special-request documentation (assistance device, special diet, anniversary). Cruise lines are bureaucratic and a missing document at check-in can cost you the cruise.

Three things you don't need to pack: a beach towel (cruise lines provide them), a travel hair dryer (cabins have them), or large quantities of cash (the cruise itself is cashless to your room key, and you only need cash for tips at small ports).
