Ever since Frank Sinatra and his pack of pals put Vegas on the star sighting map, Sin City has been the place to go to take a gander at celebs. Some can be seen at their high-profile headliner shows — Celine Dion, Shania Twain, Donnie & Marie, etc. — while others can be found bunking down at hotels like Palms Casino Resort. Home to MTV's Real World Las Vegas, the hotel features its Luxe Collection of Sky Villas and Mega-Suites with every possible extravagance, from a bowling alley to a basketball court complete with locker room. Other draws include a state-of-the-art recording studio, hot nightclubs and a high stakes gaming lounge. It's no wonder the hotel attracts big names like George Clooney, Mariah Carey, Brad Pitt, David Beckham, Diddy and Bruno Mars.
