Camp Allegro, Curacao. A bit like Butlins but each "Chalet" contains a whore, got a good bar too. Gets my vote as number 1.
Bloody hell, Campo! Was last there in the late 70's, for a beer of course, is it still going!!??
Guards at the turnstiles had baseball bats if I remember correctly, and a fair maiden insisted on prooving her wares weren't formica like the table tops.
Ah the mamories...............
Edit: That's reminded me of Mon Cherie's (Berlin), possibly not the best for drinks, but a hoot when your mate gets prematurely evicted from the bath
