My wife and I stayed at this hotel in January. The room we had was in the North Tower and was very nice. It was large, had two bedrooms, a jucuzzi tub, fantastic view (we were on a high floor) and very comfortable. We did not ask for an upgrade in the room only to be in the North Tower because it is either newer or upgraded.
We dined at the restaurant in the South Tower, which had a great view, the meal was okay but pricey due to the view.
One of the nice things about this hotel is you can walk through an overhead path to the casino and never have to go outside.
My suggestions would be to (1) pay the upgrade for the North Tower, I understand the other two towers are a bit dated and that is why I only did a four star and (2) go to the steak house in the hotel versus the one in the south tower because I think it is overpriced, expecially if you have a room towards the top of one of the towers already.
