This review is for the casino and public display areas only.
I am often at the Palazzo. Usually it's to have dinner at one of the restaurants at the Palazzo/Venetian complex. I also stop by a couple times a year to see what kind of displays are there for Chinese New Year, Spring, etc. in the Palazzo atrium before you get to restaurant row.
The casino is quite large and I find navigating it to be fairly easy. The best thing about the Palazzo for me is the convenience of the underground garage self parking.
