They are both pretty lame, I buy my grand kids the wrist bands to go on the rides at Circus Circus. If you want a thrilling ride try the roller coaster at the Stratosphere it is in walking distance of Circus Circus.
Take them to Circus Circus, which has a whole floor of carnival games and is basically a casino for kids.
i personally think you would make it in the circus and you should go right now. you could be a carnie and have weird circus friends and the onyl friends youll have would be animals. j/k. try out and if you dont make it, beg ur mom for a pony
