Not only is the queue at the Encore enormopolis so highly organized that it could have been designed by Disney's theme park division, it's also hidden from the walkway. Whereas your typical nightclub waiting area is the human version of Cup Noodles, the XS line system is one of functionality and convenience. All it's missing is a FastPass option. Encore, 702-770-0097. Fri & Sat, doors at 9:30 p.m., Sun & Mon, doors at 10:30 p.m., cover varies.
