puerto rico, bahamas, jamaica

i want to go somewhere warm in december (yes, i'm planning early!) so any suggestions? if you've been to these places would you go back? where did you stay? if you've been to more than one which one did you like better? or would you suggest somewhere totally different like aruba or something? thanks!

DH and I went to PR for part of our honeymoon. It was beautiful. We stayed at the Wyndham El Conquistador in Farjadro (sp?). The hotel is just fantastic and it has it's only private island for water sports and beach activities.
