Passengers aboard the Carnival Radiance departed Long Beach last week for an excursion to Ensenada for some fun in the sun on board and in the popular Mexican tourist destination. Unrest throughout Baja California, however, kept travelers relegated to the ship.

Hooded bandits associated with criminal cartels effectively shut down the region Friday, the Los Angeles Times reports. State officials said the group hijacked and burned at least two dozen vehicles and put up roadblocks Friday evening.

On social media, messages were circulated, allegedly by the Jalisco New Generation cartel, declaring a curfew in Tijuana, warning residents to go home or risk attack, according to the Times. The U.S. Consulate General in Tijuana issued an order via Twitter for government employees to shelter in place Friday.

According to the consulate, the shutdowns affected Tijuana, Tecate, Mexicali, Rosarito and Ensenada, which caused the world’s largest cruise line to forgo its port call on Sunday.

“The safety of our guests is our priority,” Carnival spokesperson Matt Lupoli said in an email to the Business Journal Monday.

Cruise lines reserve the right to change a trip’s itinerary at any time before or during a voyage for any reason. If guests’ vacations are “significantly impacted” by a change, Lupoli said Carnival has guidelines to provide “goodwill gestures.”

The consulate rescinded its shelter in place order just after 11:30 a.m. Sunday, well after the Radiance would have normally called at the port.

With three ships based in Long Beach, Carnival has weekly voyages to Ensenada, which offers visitors various tours, wine tastings, dining and more.

“Moving forward,” Lupoli said, “we will continue to assess the situation.”
