One star for not doing it right: A dated, early 90's decor and feel. 6:5 blackjack gives the house too much of an edge, making gambling less fun. Narrow pathways mean you're always bumping into 300 pounders who just filled up at the meh buffet and can't be bothered to clear a space for you to pass by. Cocktail waitresses are hard to find and take an hour to show up with a watered down drink. The sports book has some of the worst odds in Vegas because they know they can get away with it.
Oh and finally, how obnoxious is it to give your CEO a record bonus a few weeks before firing 400 mid level managers because "you just don't have the money to pay them"? Ugh. This place reeks of corporate greed.
Even if you're staying here, gamble at the Wynn, where they are trying harder, and it's really not much more expensive.
