First welcome to the boad.
My suggestions would be the Fla Keys, Bahamas, Curacao (just got back- trip report on the board- do a search) or Cozumel. Bonaire is great but somewhat more difficult to get to. A better description of what you are looking for would help us narrow it down a little. You want a lot of nightlife or just to dive like crazy? Big animals or wrecks?
