Would you walk down the alley in Miami at night? Common sense is all you need as Marko suggests. If you're careless you can get into trouble anywhere, not just Negril. last year had dinner with a couple of 20 something newly weds backpacking the entire island and sleeping where ever they could, mostly outside. I thought they were nuts, but they said the only time Jamaican came to see them in the dark was to bring them food or water cause they were outside. They were having the time of their young lives. Envied them after they left.
