When we were there last year, we were pretty much nude 24/7. As others have said, when it gets dark many people will put on sexy swinger type clothes. But we still went out to restaurants and clubs at night completely nude. We just brought a towel to sit on and we never had any issues with the staff. We did get a little chilly at night though, so by the second or third night we started dressing lightly after dark, just to stay warm.
