Mandalay Bay Beach

The coolest beach in the desert, Mandalay Bay Beach gets its sand-cred from 2700 tons of trucked-in Californian sand hemming in a 1.6-million-gallon pool that can generate waves up to 6ft. Kids love floating down the lazy river while grown-ups seeking tranquility can retreat to the adults-only Moorea Beach Club. For meet-and-mingle dance party action, head to the Daylight Beach Club.
