We will be there Jan 18-28, so we'll be overlapping. You need to look at the Meetup board under CSS and read the threads for Jan 2012. It's a pretty full week, with some fun people; and it has photos of many of the couples. You should report there.
No tipping required or allowed
Try Casanova once or twice
Definately eat at Bella Vista on the beach a couple of nights
Wednesday is Lobster night and all the resturants so if you like lobster-go for it
If you like to smoke cigars, drop me a reply
If you like nude sunbathing, or want to try, check out Sunset Beach (SSB)-lot's of freindly, fun outgoing people there
You'll get a lot more advice from the multi-year folks over on the CSS Meetup page
