With feathered showgirls, world-class comedy acts, magicians, music and more, the shows in Las Vegas have always been part of the draw. In the last ten years acts like Cirque du Soleil and Criss Angel's Mindfreak have really upped their game, and making time for a show is considered a must these days for tourists. Most high-end shows are advance-purchase reserved seating, and you can book them at the same time you book your travel, but there are plenty of smaller acts that you can book the night of, or buy at the door. Your concierge is a great resource here, so be sure to ask about deals and discounts.
