I've been visiting SXM as a "single" for twenty-five years, and there's a reason it's called "The Friendly Island". You'll have no trouble meeting people. I'll second the Driftwood recommendation, and also in Maho, you could check out the Hole in the Wall (live music just about every night) and the Beer Garden. If you're down in Simpson Bay check out the Tap and Still - they have Karoke on Thursday nights and that usually draws a social crowd. I'm probably going to upset some people with this - but generally I've found the Dutch side to be more sociable - I thihk the French side lends itself to more of a romantic vacation. Just relax - you'll meet as many people as you care to, and you'll have a blast!
