Carnival has a list of banned items that you cannot bring on a cruise. For example, you can’t bring weapons, fireworks, liquor, any appliances with a heating element, or hoverboards, just to name a few.

As an example, Royal Caribbean offers an itinerary aboard Rhapsody of the Seas, departing from San Juan, that features port days in St. Thomas, St. Croix, St. Maarten, Antigua, and Barbados — all in a 7-night cruise.

Carnival Corp. is putting the finishing touches on, not a new ship, but a new destination for cruise passengers. Beginning in July, Doral-based Carnival will send ships between PortMiami and Celebration Key, a private development in the Bahamas.
