The girls return to Las Vegas (with Hef this time!) for two very important occasions: to promote the new Playboy Club at the Palms Hotel & Casino and to preview designer Roberto Cavalli's sexy "bunny couture" (an update on the classic bunny costume that will be worn by cocktail servers at the Playboy Club). Both events are hotter than the desert sun. The Palms' new Playboy tower is stunning, housing Playboy-themed casinos, suites and the first official Playboy Club in decades. During their stay, the gang embraces the rest of Sin City, too, checking out a wax replica of Hef at Madame Tussaud's, partying with hotelier George Maloof and playing some B-ball inside a hotel room's full-size basketball court! Then it's off to dinner with Cavalli and a fashion show for the new Playboy Club's bunny costumes--starring Holly! It's the perfect way to usher in a new era of Playboy.
