Carnival Cruise Lines will be staying away from Mexican ports of call through mid-June because of the H1N1 flu. Previously, the line said they would return to Mexico on May 11.

Altogether this includes some 16 ships in the Carnival fleet. The ships most affected include Carnival Splendor which is sailing a modified course on the West Coast from Los Angeles to Astoria, Victoria and Vancouver British Columbia. Ships that previously went cabo San Lucas and/or Ensenada are mostly just visiting the island of Catalina off the coast of California.

Caribbean cruises have substituted Montego Bay, Jamaica, for Cozumel on Conquest out of Galveston. New Orleans' Fantasy is going to Key Wst, Nassau and Freeport Bahamas. Carnival Legend out of Tampa is going to Grand Cayman, Belize and Roatan while Inspiration is going to Grand Cayman only.

Carnival Freedom is substituting Belize for Cozumel. The ships sailing out of Miami to the Western Caribbean are using Key West in place of Cozumel.

Guests who want to sail on a different trip can receive a refund in the form of a future cruise credit equal to the full amount paid for the voyage.
