American Cruise Passenger Kills Beach Mugger

The U.S. State Department provides updated information on threats to American travelers.

For Costa Rica, it advises that theft is common.

In the Bahamas, a popular cruise ship destination, visitors are instructed that "crime and violence has moved into more upscale tourist and residential areas."

According to the State Department, Bermuda "has a moderate but growing crime rate."

Travel experts advise tourists to enjoy and educate themselves, because they must remember, they are targets.

"We have to understand that most people who live in these countries are fine, honest, law-abiding people, but there's always going to be a small percentage of that are looking to target travelers because they're easy marks," Coffey said.

Carnival said that for the time being, it is doing no more stopovers in Limon, Costa Rica. It will make stops at Roatan, Honduras, instead.
