So I was watching it the other day and from what I could tell it seemed to me that they were staying at the LVH. Although when Woody leaves Demi in the penthouse with Robert Redford he goes down to a rainforest type cafe and has a drink, he then has second thoughts and runs upstairs to find them gone. He finds out from the maid they are leaving in a helicopter, when he gets up there and the helicopter takes off you can see MSS and the Lady Luck. Things like that annoy me in a movie, so which hotel did they take off from? Binions or Freemont maybe?
