I have gone out in Negril alone, including the Jungle. Don't get drunk, don't get to cozy with anyone, and go home at a reasonable hour or if the atmosphere becomes tense for some reason. I love the atmosphere at the Jungle... it's fun dancehall, great people watching, and some talented dance crews "facing off"... if not staying close (hotel) to your night spot, take a taxi. You can try to establish a relationship with one driver during the day and set up a pick up plan or get their number, or just look for a car with a red plate. I hate the motorcycles, especially after sunset- they are the only thing on the road that makes me leery. Have a blast, don't be a drunk a-hole and you'll be fine!!!
