Las Vegas calls itself the entertainment capital of the world and many casinos will charge you for it. Some of the best attractions in Vegas are free! The Circus midway has shown once an hour from top circus performers around the world. At the Rio they have an amazing show in the casino which runs frequently. Downtown has a wonderful light show above the mall, and again it’s free! Two other great attractions are the pirate show at Treasure Island and the fountains at the Belagio. In fact walking through the casinos and seeing the decor and themes can be a thrill in itself. You really can see Vegas for very little, but it is designed to make you spend money.
