We were at the Mirage in Jan, we paid $299 a night for a one bdroom pent house suite. For the price you can't beat this, big window a fully view of the strip, love those automatic curtain. A very quiet surrounded atmosphere up there, try to avoid the room service there.
We just a book a grand penthouse one bdroom suite at the Bellagio in August (I believe it's a second best from the Villa) $1200 a night for our family reunion. I believe the only two suite that are not listed at the hotel website are the Villa and Grand suite.
Will keep you update on our next stay at the Bellagio
