(This is probably 4.5 stars to me.) What a wonderful place! This is a beautiful hotel that's holding its own against age. The rooms/suites are excellent. The one we were in was a split-level room, with comfortable living and bedroom areas. The furnishings were comfortable and clean. [I know I said "comfortable" twice, but it's what stands out to me.] My wife would harass me if I failed to mention the electronically controlled draperies, which I thought were an excellent touch.
This hotel has a great center-of-strip location (although it's toward the end of the central section of major hotels), and loads of shops and restaurants within its warren of halls. There're also two -- or at least two -- large casino spaces, representing the Venetian and the Palazzo. The staff is friendly and efficient.
I've stayed in a number of places in Las Vegas, but this is the first place to which I've _really_ wanted to return.
