What to Pack for a Caribbean Cruise with Kids

Cruising with kids is an effortless vacation once onboard, but cabin space is tight and cruise lines enforce strict prohibited item policies. Preparing magnetic organizing tools, port excursion dry gear, and seasickness remedies ensures a smooth voyage.

Essential gear for a family Caribbean cruise

  • •Cruise ship stateroom walls and ceilings are made of steel. Heavy-duty magnetic hooks (rated 25–50 lbs) stick directly to the walls, creating instant vertical storage for wet swimsuits, lanyards, daypacks, and sun hats.
  • •Standard household power strips with surge protection are strictly prohibited on all cruise lines for fire safety. Bring a cruise-approved non-surge power strip with multiple USB-C ports.
  • •Pack lanyards with clear ID card pouches for the whole family. Room keycards (SeaPass, Key to the World) are required for stateroom access, onboard purchases, and boarding/disembarking at port stops.
  • •Bring towel clips or towel bands. Sea breezes on the top pool deck regularly blow towels off sun loungers while families are in the water.
  • •Embarkation day carry-on: Checked luggage can take until 6:00 PM to reach your stateroom. Pack swimsuits, sunscreen, medications, and phone chargers in a daypack so kids can head straight to the pool deck upon boarding.
  • •Motion sickness prevention: Pack Bonine (meclizine) for adults and kids age 12+, chewable Dramamine for younger children, acupressure Sea-Bands, and ginger candies.

Common cruise packing mistakes

  • •Packing clothes irons or garment steamers. These are fire hazards and will be confiscated from your luggage at terminal security.
  • •Packing only 1 swimsuit per child. High humidity at sea means swimsuits do not dry overnight inside staterooms without balcony breeze.
  • •Forgetting passports or government-issued birth certificates for closed-loop cruises (cruises starting and ending at the same US port).
  • •Forgetting that infant swim diapers are prohibited in standard cruise ship pools by US Public Health law; toddlers must use dedicated splash zone areas.

FAQ

Can you bring snacks and drinks on a cruise ship?

Most cruise lines permit passengers to bring non-perishable sealed packaged snacks (pretzels, granola bars) and a limited quantity of sealed non-alcoholic cans (e.g. 12 cans of soda per stateroom) on embarkation day.

Do kids need passports for a Caribbean cruise?

On "closed-loop" cruises (sailing round-trip from the same US port), US citizens under 16 can travel with an official state-issued birth certificate, though passports are strongly recommended for international emergencies.

How dressy are cruise formal nights?

Formal or "Dress Your Best" nights are optional on modern cruises. A collared polo shirt and dress shorts/chinos for boys/men and a sundress for girls/women is fully acceptable.
