We Walk on beach for later dinners constantly, unless you are quite late there are lots of other people out. I know if I say "nothing has ever happened" there will be some comments, but I don't understand why "the beach" seems to be different from walking anywhere else. Walking anywhere that is desolate and dark is not recommended but that could be the beach, the road or anywhere. If it comes to it where I can't walk on the beach in Negril at reasonable hours I will no longer be going to a Negril, walking that time of the night on the beach is one of the best parts about tropical places.
