Western Caribbean
Both Carnival with their Ecstasy cruise line and Royal Caribbean with its Voyager of the Seas offers a variety of cruise packages that explore the Western Caribbean, with popular ports of call including Cozumel, Mexico, Progreso on the Yucatan Peninsula, Grand Cayman and Jamaica. Royal Caribbean also offers trips that stop through Honduras and Belize. The cruises vary in length, with popular four, five and seven-day voyages available.
Eastern Caribbean
If you're looking to experience the Eastern Caribbean, board a Carnival Conquest Cruise Ship, otherwise known as the Fun Ship. The cruise line's Eastern Caribbean cruise includes stops in popular destinations in the Bahamas, like Naussau and Freeport, with a stop in Key West as well. The Eastern Caribbean cruise is only offered in a seven-day package and runs from mid-May through the end of January.
Exotic Destinations
While it's most common to cruise from Galveston to ports of call in the Caribbean, you can still find more exotic destinations thanks to Royal Caribbean and their 14-night Transatlantic Cruise. You'll sail on the Voyager of the Seas to ports of call in Nassau, Bahamas, Ponta Delgada, Azores, Malaga, Spain, Cartagena, Spain and finally, Barcelona.
