The hotel was great. My only issue was after checkout, I realized I had left my swimsuit hanging on the hook in the bathroom. My Fiancé called a few hours later to ask and it was never found. They don't seem very honest to me considering it had to have been found by someone.

My one-night stay was comfortable; the room was clean and adequate. The morning breakfast was very good and the service excellent. The only downside was because of some refurbishing projects the restaurant was closed, no hot tub and the pool was not functioning. Great view across the river.

I'm not a huge fan of the location. And it is a dry casino, meaning no alcohol. But the venue was fun for a concert. And the staff were quite nice.
