Nothing new with Circus Circus. A few years ago, I stayed there for a night and got bedbugs.
The Imperial Palace was usually my place of choice in my single days because my room was often comped. That place was an even bigger dump than Circus Circus, but I never got bedbugs there.
We stayed at the Imperial Palace about 15 years ago. Woke up the next morning with a guy passed out in front of our door. Place was a dump. Wrote a letter after we got home and they sent a voucher for a free stay. Mailed it back and told them to keep it.
