Born and raised in Vegas, I've been going to VooDoo Beach even before it was called VooDoo Beach. I used to come here as a kid to play in the pool with the sand, and I'm happy to see that it's still around to this day.
However, The Rio definitely has changed their marketing strategies from keeping it as a family-oriented pool to one that is a little more risque and racy. I would recommend everyone who does have kids to be wary of taking your family here nowadays, for they do have women in skimpy bikinis dancing provocatively to the DJ music to promote VooDoo Beach and Club upstairs (at least this was what I seen the last time I was here).
What I like about VooDoo Beach the most is there is comfortable space set between the chairs. There are some pools with chairs touching each other to where you could literally reach over to the stranger next to you, but the pool deck here is wide enough so people have the opportunity to stretch a little bit. There are three outdoor bars, an outdoor grill to grab food, and a kiosk for pool amenities, all in short walking distance no matter which pool you're located by.
Local women are free Fridays through Sundays. I often come here to unwind since this pool doesn't get too mobbed with too many people, but is still nice to sunbathe and enjoy the DJ. There are plenty of cocktail waitresses to wave down if you don't walk up to the bars yourself, and the staff is pretty friendly and attentive.
