Negril is a fantastic choice. I understand that RIU is a fantastic resort but I concur with the boardies telling you to get off the resort and visit real Jamaica. So many great places so close to RIU. Bring sunscreen, bring bugspray (you might never need it) and also bring your basic common sense and street smarts. Wandering around Negril requires about the same basic safety concerns as visiting any major city. Just pay attention, know where your wallet is, and most of all don't fear the street hustlers. Jamaicans by nature have a quick wit and a great sense of humor. I see so many tourists trying to avoid the Jamaican street folks and that just never works! It is easier to make friends and be courteous. Everyone wins.
