Carry a personal alarm and whistle....are you serious? No disrespect meant but if I had never been to Negril and read your comment, it probably would of scared me away from coming, especially as
a solo traveler. A women usually has a real good intuition ,that's what you have to follow including common sense. Using a door alarm is a fine idea, and making sure your doors are locked at all times, yes...but I'm not gonna feel like I have to barricade myself in all the time.. The day I have to use personal alarms, whistles, mace etc around Negril is the day I stop going....for real...
