Getting approached on the beach is certainly one of the downsides of visiting Negril. There are countless upsides. There is solid advice in this thread that I have used over time that has helped to deal with the situation. One other strategy that my wife and I use is walking at a fast pace and with purpose when cruising the beach. It's not much unlike the "culling of the heard" principal, the slow movers are easier prey. One of these days, age will catch up with us and we will need a new strategy!
