When I used to stay in Negril during the 90's, I stayed at the Negril Yacht Club that was owned by my good friend Chuck who was from my town in Florida.
I picked up a brochure in the office with the only map I could find of Negril at the time. I thought you might enjoy seeing it yourself. I particularly like the way they show the interactions between Jamaicans and the tourists. Hope you enjoy.
Peace and guidance.
