Once about 6+ years ago there were a few women drinking topless at the bar and they seemed to be part of a group and the group was having a good time with it.
Fast forward to 2 years ago we were there and there was one topless woman...it was a bit awkward. The expansion has changed the 'beach bar' vibe at the end of the runway. We didn't have a good experience at Driftwood. Just my personal experience.
