He probably got a rate for 4 nights, but forgot it was leap year when he posted it was 3 nights. Even so, $200 each is not a good deal for Circus Circus. Even though it's off strip, I'd rather stay at a place like the Orleans. The chicks are cuter, the waitresses are much better looking, and it's much more of a party at the Orleans than Circus Circus. Just for grins, I checked those 4 days, and it's $580 per room, less than $150 each person, 4 up. It's just an example, I would imagine you can still beat that Circus Circus price at a place like Harrah's or Flamingo, etc.
Don't forget to rent
