The promoter in Aria talked us into checking this out with a "free" pass. Once in the line, further away, told the pass allows my wife in for free, but I can get in for half off the normal $40 fee and for $20 more my wife gets free drinks. Simple uncool bait & switch. Still, since we were already there we went for it.
Second reason for the low score was that the inside was lame. Too loud, little space, left after 15 minutes for greener pastures.
