Aww, everyone is so harsh on Circus Circus!
I kind of like this seedy little place. The location is great and I like the layout inside. I highly recommend the Slots of Fun out back - pure gambling bliss at insanely cheap prices.
The Adventuredome is great for kids, though last time I went I found it pretty lameo. The carnival games area is the best though - first time I was here as a kid I won SO many stuffed animals that I had to give some away because I wouldn't have been able to get them all home on the plane.
Anyway, when you go to Vegas you at least have to visit Circus Circus. It's a Strip institution!
