To be safe, keep your hotel or vacation villa door locked at all times, stick to well-lighted streets at night, and use the same kind of street sense that you would in any unfamiliar territory. Don't wander the streets of Charlotte Amalie alone at night. If you plan to carry things around, rent a car—not an open-air vehicle—and lock possessions in the trunk. Keep your rental car locked wherever you park. Don't leave cameras, purses, and other valuables lying on the beach while you snorkel for an hour (or even for a minute), no matter how many people are nearby.
