I'm sure this place is beautiful as a venue, but as a standalone museum, it is not worth the $15 entrance fee per person. You walk up one set of stairs and are shown a tiny gallery where they have traveling exhibitions. The exhibition at the time we were there was that of some "famous" child painter who just put random brushstrokes on the canvas and some proud mom declared it "art."
The bulk of the palace is unable to be visited. Only the primary ball room which is absolutely gorgeous and massive. I bet all the 5 star reviews are of people listening to concerts in that hall. Absolutely stunning. However, while viewing, you can spend maybe 5-10 minutes in there before you move on to the Doge's Chapel... which is also gorgeous, but small and worth another 5-10 minutes of time. All in all, we were out of there in less than 30 minutes and while we love the rooms we saw... we just expected more like the Royal Palaces in Genova and Torino.
