Sin City's Most Famous Places to Cool Off March 11, 2012 - Known for decadence and debauchery, the pool scene in Las Vegas is almost as big of a draw to the desert city as the gambling. While some pools, like Vdara, are open year-round, many more make their annual debut when spring arrives, complete with huge parties to celebrate. Keep in mind the vast majority of Las Vegas pool-centric dayclubs only admit guests 21 and older. As the weather heats up, so do the parties.
