Civil unrest and violence around Puerto Vallarta led to cruise lines canceling ship calls there.

The Celebrity Infinity bypassed the Mexican port on May 10 for a day at sea, spokeswoman Cynthia Martinez said. On May 12, Royal Caribbean International’s Jewel of the Seas will substitute a sea day for Puerto Vallarta.

In a statement, Royal Caribbean Cruises Ltd. (parent of Celebrity and Royal Caribbean) said the decisions were made “due to the recent episodes of violent civil unrest, stemming from criminal gangs that have engaged in armed conflict with local authorities.”

Disney Cruise Line distributed a letter to passengers on a 14-day Panama Canal cruise aboard the Disney Wonder explaining that the May 12 port call was being canceled, citing “several reports of unrest in the area around Puerto Vallarta.”

Disney said taxes, fees and port expenses associated with the visit would be refunded to the original source of payment used by the passenger to book the cruise.

The Carnival Miracle will continue with its scheduled May 12 stop, but some shore excursions have been canceled, a spokesman said.

The U.S. State Department issued an updated travel warning for Mexico on May 5 detailing the “risk of traveling to certain places in Mexico due to threats to safety and security posed by organized criminal groups in the country.”
