All right SF, time to tap your collective wisdom. I'm looking for specific recommendations for a holiday destination for two in the Caribbean. Not too fussed about the location, just that it be reasonably accessible from Miami or thereabouts, with regular commercial scheduled air service. What I'm after is the type of resort - I don't want those gimmicky all-inclusives, but rather am after something a little more secluded. Villa with a private (preferably infinity) pool, lux but no need to overdo it. I realize these places don't come cheap, but can I do this for $500 a night or less?
