I didn't watch the show, but they were discussing it yesterday on local radio, Do they really expect to fill the show every night? Tickets start at $87 and go to $200 per seat. As a comparative example, on of the more popular shows, which I've forgotten the name of, but it's water based, is around 100 a seat. They had someone on whose daughter works there and the salient points are it's sold out to May, but, a lot of those tickets were sold to other casinos to give out to the high rollers as perks.
The radio people did sum it up real good in one sentence:
"She's a wonderful singer.......but she's still a twit".
