Great place to stay for travel or some casino fun. Parking is extremely easy and convenient to the hotel. Check-in and check-out is very fast. The hotel is very well kept and taken care of. Rooms are very spacious. The casino restaurants have great food options available. All of our meals were very good. I would definitely recommend staying here!

The only 2 things that I would say I didn't like is that the room didn't have a microwave and the pool closed so early

Overall stay was fine. Room was clean. The floor lights do not shut off. The bed lamp switch was broken so it wouldn't shut off, either. Called and requested an adjoing room for my Grandmother. Was told they do not have adjoining rooms at this property. Requested again at check in and was told not available. They put us in 2 rooms across the hallway from each other...one of them having an adjoining room door. Beds were comfortable. Restaurant was fine.
