Nirvana is located within the hard rock Hotel and Casino. It is right next to rehab. Despite its location, it actually is very peaceful and relaxing. And ode to the 90s band and the meaning of the word. It is relaxing, peaceful, and also plays 90s grunge music. There is a full bar with cocktail waitresses walking around and serving you. When I was there both times, there were kids there and also families playing in the pool possibly an older crowd as well. Depending on the time that you hit the pool. The best advice, is to get there early to secure a spot. There aren't that many chairs. It's definitely a different pool experience than rehab! Review to follow about rehab!
