So you're traveling to the World Series of Poker with people who don't play poker or gamble. What can you send them off to do without you while you're playing poker? Plenty.
Here's a sampling of the many activities available in Las Vegas for the non-gamblers.
Shows
There is more live entertainment in Las Vegas than in any other city in America except perhaps New York City. Some of it is "permanently" housed in a specific casino, with a consistent weekly schedule. Other shows are occasional, coming into Las Vegas for a limited run and in some cases for one appearance only.
