Get out as much as you can. Try as many bars and restruants as you can and get away from negril and go to one of the waterfalls or other attractions at least once. Negril is great but there is so much more to see that lets you experience more of the culture and beauty of Jamaica. Just use common sence as to not put yourself in situations that you wouldnt put yourself in at home and do it safely. To many people never venture out from where they stay and have no idea what they are missing out on. Jamaica is a beautyfull country and most of the people there are really friendly and kind. Enjoy it, respect it and take in as much as you can and you most likely want to return as often as you can. Some of my best days in Jamaica were days i just went off with no particular destination in mind and no expectations and had ended up having a wonderfull time
