The palazzo is my favorite hotel/casino in Vegas. Rooms are comfortable and have a art-deco type of vibe to it, the service is generally on point, and the casino is usually not insanely crowded.
The only complaint I would ever have is that they don't have their own poker room. And as someone who spends most of their gambling time at the poker tables - its a pain in the ass and a long walk to the venetian side.
