Last three trips have been to the Palazzo. Find a good deal for the "Prestige Level" which gets you a private concierge level with free breakfast, free evening drinks, and free light dinner. You can ask them for lots of other perks if you are into gambling (which I don't do).
The savings on breakfast, drinks, and dinner easily saves me $75 a day for me, and $75 for my wife. Worth every penny and really awesome rooms with huge sitting area, beautiful bathrooms, remote control curtains, nice views, etc...
To each his own, but if you stay there, its hard to go somewhere else.
