I have done it 3 times.  First time was okay but last two times was a bore.  The one with Caesar as the master of ceremony was particular bad.  Perhaps I am jaded from seeing all the Cirque Du Soleil shows in Vegas which are far better.  Also they cram you in like sardines and the seating are not that comfortable and have poor line of sight for the show, especially in the booths.  The food was okay.  I would not repeat again
