Packing for a cruise comes with plenty of decisions, and food is one area where Royal Caribbean has firm rules. Knowing what's allowed — and what isn't — before you reach the embarkation terminal can save you from an awkward confiscation moment and keep your luggage moving smoothly.
Homemade foods are a no-go across the board. Royal Caribbean cites unknown preparation conditions, temperature control concerns, and cross-contamination risks as reasons for the ban, so leave the cookies, sandwiches, and meal-prepped casseroles at home. Fresh fruits and vegetables are similarly prohibited, since they can carry foreign pests or plant diseases that might threaten agriculture at ports of call. The cruise line sources its own produce through approved suppliers, so you'll still find fruit and salad bars throughout the ship.
When it comes to drinks, guests of drinking age may bring one sealed 750ml bottle of wine or champagne aboard on embarkation day, but beer and hard liquor are prohibited entirely — any alcoholic beverages seized at embarkation will be held and returned at the end of the voyage if they're in an original sealed package. Non-alcoholic beverages are permitted, but capped at 12 standard cans, bottles, or cartons (up to 17 oz. each) per stateroom. Milk and distilled water needed for infant, medical, or dietary purposes are allowed on top of that limit.
A few other food rules are worth noting: opened or partially consumed packages of any food won't make it through security, and perishable items — think fresh meat, seafood, and dairy — are banned as well. Standard stateroom mini-fridges aren't equipped to safely store those items, and the cruise line can't verify how they were handled before boarding. As for snacks and packaged goods you do bring, they must be sealed and in limited quantities.
Beyond food, Royal Caribbean's broader prohibited items list covers things like steamers, irons, candles, surge-protected power strips, and illegal substances, including marijuana in any form. When in doubt about a specific item, the cruise line recommends checking its official prohibited items list before you pack. This article draws on reporting from Royal Caribbean Blog.
