This was my favorite thing we did in Las Vegas.
The place is HUGE with 3 pools that are elaborately designed. In the pool itself there are built in benches, tables, and decks that show this pool was designed to be a dayclub. It was always easy to get in the pool and find some space to sit and set your drink down at. Another big benefit to this pool is many of their daybeds are actually in the water or even have their own personal small pools.
There are several bars scattered through the place. They all made great mohitos. Never had to wait more than 5 minutes even though it was packed. They have a very nice bag check for $10 that you can go to as much as you want (at Daylight they wanted $40 for a small locker).
Our groups favorite thing to do here was just watch the people. Who knew you were supposed to wear high heels to the pool? If you got something to show off this is the perfect place to do it, otherwise just sit back and enjoy the show ;)
