Stayed mid-week for a pretty reasonable price ($110 a night) -- had a standard room with no view, but enjoyed it. The interior of the room was well designed, the maid service was good.
Having stayed at a real 5 star hotel where you don't have to tip obscenely for exceptional service, I can't give this 5 stars. But all the same, we really enjoyed it and thought it was beautiful, fun and a classic Vegas experience!
