I was pleasantly surprised when we fought our way through the crappy parking and crowded hallways of Circus Circus to get to Adventuredome! No admission to get in and look around. They crammed a lot into the space! Rides for kids and adults, plenty of arcade games, mini golf, a midway to play games and win prizes, and even an old school arcade (all you can play for $6). You can buy a wrist ban for the rides for the day, or pay per ride. It's no Disneyland or Bush Gardens but for the price - it's actually not bad. ...and you're not outside in the heat at some carnival either. Great place for kids of all ages, and even those adults who still like this stuff!
