Palazzo is one of my top 3 hotels in Vegas. It's basically a tricked out version of Venetian with top of the line options and much more to offer. The lay out of the rooms is just like Venetian but they are much nicer, with three flat screens and much nicer furniture, decor, amenities. The restaurants are much better at Palazzo too, especially Cut, Bouchon, Delmonico, etc. The sports book is nice but the casino in general is not so good. Cost of rooms are about the same as Venetian I believe so if you have to choose between the two, choose Palazzo.
