Rehab Hard Rock Hotel Las Vegas is the part at a pool. Don't plan on swimming because the whole pool is full of people standing and drinking and dancing. There are always famous DJ's and celebs that stop by and the music is loud and pumping non-stop! Get a large drink cup because it is so busy getting a drink takes forever. It is expensive so if you can meet one of the promoters (you'll see them hanging around giving tickets to girls) that will save you serious money. We met some really cool guys that got us in. If you want to party at the pool Rehab has got it!
