Caribbean - if you are looking for that more secluded island feel I would look at Turks & Caicos, Anguilla, Curacao. Dominica.
If you want a more tourist type thing, the Bahamas, Jamaica, Barbados etc.
Was lucky enough to have a working trip there during the cricket World Cup.
If you want something that is completely different yet fantastic, look at Cuba. You won't get the luxury resort but the place is just a fascinating place to see.
What about the Greek Islands?
