Just Google JAMAICA GAY LAWS and all of your questions will be answered. Not a pretty picuture! None of my Pink bucks will ever be spent there. I have also heard very discouraging things about Hedonism Resorts. Here is an excerpt form Frommer's Guide:
Jamaica is the most homophobic island in the Caribbean, with harsh anti-gay laws, even though there's a large local gay population.
Many all-inclusive resorts maintain strict no-gay policies. However, Hedonism II in Negril does allow gay travelers. So does the Grand Hotel Lido in Negril. Still, avoid open displays of affection -- such as handholding on the streets -- in Jamaica: You could be assaulted for trying it.
