Parking is valet only so it's okay. We ate in the onsite restaurant . It was good/aveerage--nothing out of this world but it everyone in the bar was friendly. My only issue is I asked for a room with a sofabed and did not get a room with a sofabed.

First I booked for two queen size beds we got doubles. There was no remote. We called and they didn’t bring one up. Saturday night we called again and they finally brought one up. The rooms were clean and nice. Just wanted what I paid for.
