I've stayed here many times during my lifetime. As a kid, this place is awesome. As an adult... only awesome for the price. If you're an adult with kids, probably a great place because your kids will love The Adventure Dome and you'll enjoy seeing them smiling and happy. Plus, it'll wear them out and they'll go to bed early.
I haven't stayed here in about 8 years. It really looks beat. They need a lot of upgrading. First thing you'll notice when you are checking in is the receptionists are, to put it kindly, not the hip well dressed type that you would find at the more upscale hotels. You'll also notice the girth of most of the corn fed guests.
I got a non-smoking room, but the stench of cigarette smoke still permeated throughout the entire hotel. So not used to that. What can you do?
The pool, trust me. Pass on that. Even if you have kids.
Didn't try any of the dining offerings. Judging from the reviews on here, I wasn't missing much.
What did I like about Circus Circus? The memories I've had as a kid here, the price, internet included as part of the stupid Resort Fee (which is only $7.50 a day) and the room, aside from the stink, was pretty decent.
