I recommend the RIU in Negril! I spent a week there a couple years ago and my wife and i both loved it. Never have to leave the resort! We went into town a couple days, went to Rick's Cafe, ect. Never had any problems, mon! Lol
The Jamaicans are different people, they are pushy with whatever they are selling. Just don't touch anything you don't care to purchase, Best advise I will give. If you go down with the goal of relaxing and having a good time you will have a good time.
