13 Resorts With Incredible 24-Hour Pools

You didn't think we'd forget Sin City, did you? This glam, grown-up hotel has an open-air rooftop with private cabanas and a pool that (much like the crazy city around it) never closes. The WET Deck, as it's called, offers gorgeous views of the blinky city and the desert mountains, and it's dotted with cool art from local and international photographers and muralists. Celebrate your big win at the blackjack table with a few victory laps, or swim off that utter poker fail.
