Princess Cruises is cutting ports of call to Puerto Vallarta and Mazatlán along the Mexican Riviera, despite the fact that the U.S. Department of States omitted the two cities on its updated Travel Warnings list. Princess claims broad security concerns present in the region as the reasoning behind the re-routing, and the company isnt alone in its concerns. Carnival, Disney, and Holland America have also canceled calls to Mazatlán this year, citing similar security concerns. The news of Princesss decision has hit hard in Mexico, which just launched a weeklong anti-crime campaign in an effort to win back a portion of the tourism revenue its lost as cruise companies re-route. The November 19, December 10, and December 31 7-night cruises aboard the Sapphire Princess will alternatively stop in Ensenada and add a second day in Cabo San Lucas.
