The Voo is a secluded dayclub at the Rio offering an adults-only atmosphere. European (i.e., topless) sunbathing is allowed by guests who want to avoid tan lines. Seven cabanas and numerous daybeds surround the waterfall-packed pool. Go-go dancers, flair bartenders and some of the hottest DJs in Las Vegas are among the amenities at this vibrant pool club. Poolside spa treatments round out the VIP options. Two full-service bars -- the Cruzan Island Bar and VooDoo Beach Bar -- and a dining menu are also available.
