Azure is Palazzo's "adult pool" for 21 and over guests. We checked this pool out twice but stayed for a total of no more than 15 minutes...
The first day, my 31 year old cousin couldn't get in because she forgot her ID (yes, she looks young). The second day, we were disappointed to find out as we entered that there is a $50 minimum food and drink charge per pool chair (the same ones that are free at the "regular" Palazzo pool) and a $300 minimum charge for the big square lounging cushions that can fit a few people. The food (by Wolfgang Puck) and drinks aren't cheap but that is still a lot of itmes to purchase for one chair... There was a free area in the shade in the back corner of the Azure area...
It was nice to have a dj that was not too insanely loud but the music was a little bit too techno for me. I preferred the music (and the scene in general) at Tao Beach. I might recommend Azure if you really want to get away from any children though and are probably in your late 20's or early 30's...
