The band of theatrical acrobats has set up camp permanently in Las Vegas, running no less than seven different shows simultaneously at various locations around town — everything from the classic Mystere to the King-themed Viva Elvis. Skip the erotic, 18-and-older Zumanity and the 12-and-over (and poorly reviewed) Believe, and splurge on Beatles Love at the Mirage or O at the Bellagio. Keep in mind that kids under five aren’t permitted into any Cirque show.
