Rehab at Hard Rock is far and away the best of the Vegas clubs to hang out in on a Sunday afternoon. After three successful years of poolside partying, the Hard Rock added a new bridge, more cabanas, a new stage and season passes. For $1,200, pass holders can get into every Rehab without a wait, and bring two guests with them. Mere mortals can pay a cover. Once inside, you’ll have to make the decision on where to mark your territory. These days, it’s not as much about how much sun you’re getting as it is about positioning for optimum viewing. L.A.’s most beautiful people and connected locals put on their best bikinis, whether they have a hangover or not. The lagoon quickly fills up with partygoers who refuse to leave Vegas without bringing home a story to brag about. This party makes all your trips to the gym worthwhile.
