I struggle to rate Voodoo because some aspects were great and some were so-so.
We decided to check out the place on a Friday night since it was already midnight and we had just arrived in Vegas. The guy at the front asked us if we were locals (apparently it was locals event). I said no, but we could be for one night *wink*. Whether it was my answer that got us in for free, or the fact that we were two young women, we were escorted to the elevators that take you to the 51st floor of Rio.
The view, 5 stars hands down. I felt like a baller hanging out on the huge balcony and partying on the outdoor dance floor, and isn't that what Vegas is all about? The music playing outside was ok--decent mix of top 40s and popular old school hip hop jams that I love. The bouncers and bartenders were really friendly-- a major plus since most of the time I just expect nightclub staff to be complete jerks.
The crowd is pretty mixed, which I appreciated because I don't know if I would have survived a night in a frat boy meat market environment that many other Vegas clubs tend to be. As for poppin' factor, I'd have to give it 2 stars--not crowded at all, which might be good for those that like having room to dance.
Overall, a good place if you're just looking for a chill night of lounging and photo opportunities.
