Not that other reviews unduly influence my own, but the people on this page are utterly entertaining. And in the spirit of not throwing in a statistical outlier, I won't put up a 5-star here. But I had a great time here.
Mind you I did not stay here - I am cheap, but not THAT cheap. My friends and I wandered over here around 11 PM looking for something to do and found the second level with all the carnival games. We had a blast with the horse racing game (where you slide the ball down the ramp and if you drop the ball in the red hole, the horse advances farther), the water race (shoot the clown's mouth), and a wide variety of games I had not played since I was 12. Granted the folks working here looked completely miserable (it was past midnight by the time we got to some of them) and I felt bad for them since there wasn't much business. But I really loved this place as a kid and returning here made me nostalgic for a time of my life that is long gone, save in my mind.
Don't be so cruel to this place, Yelpers! Just don't stay here and you'll be fine. It's only a 15 minute walk from the Wynn, where I was. Now that's a fine place to sleep. ;-)
