Carnival Cruise Line has repositioned some of its ships so that the cruise line can offer a greater number of short cruises to the Western Caribbean. The changes in ports are effective immediately, and the cruise line is already offering tickets for its new cruises.

The Carnival Valor now calls New Orleans its new home, where it has begun offering four- and five-night cruises to Cozumel and Progreso, Mexico. The five-night cruises will include a stop in Progreso.

The Carnival Dream, on the other hand, will now position itself at the Port of Galveston in Texas. The Carnival Dream's four-night cruises will include a stop in Cozumel whereas the five-night cruises will include an additional stop in either Progreso or Costa Maya.

The moving of the Carnival Dream and Carnival Valor occurred at the same time that Carnival changed the homeports of two of its East Coast-based ships. The Carnival Magic is now based at Port Everglades, where it will begin offering six- and eight-night Eastern and Southern Caribbean cruises. The Carnival Conquest now calls the Port of Miami home, where it will begin to offer weeklong cruises to the Eastern and Western Caribbean.

It is not unusual for Carnival to change its ships' homeports periodically. Many people will use the same port each time that they take a cruise. Changing the ships and updating the itineraries that originate from the port encourage repeat customers who want to try out a new ship or visit different destinations to choose Carnival again. These strategies keep everything fresh for passengers and the crew members alike.
