Sorry, I assume you meant this all to be in one post??
Generally resorts in Jamaica are not really 5 star. Some exceptions might be Sandals brand new overwater bungalows. However, from what I hear, they are REALLY expensive, and sold out for quite some time ahead. Sandals resorts are probably the class of JA resorts though. Also, not sure if you're interested in clothing optional, but if so, a brand new option is the latest iteration of Grand Lido Negril, which is a small part of a larger resort there.
