I liked that the front staff made sure that check in process quick and efficient. No issues. If anyone is arriving after 11pm and need to find parking in a garage, good luck. All the nearby lots closed by 10pm.

We were there for a competition and the hotel staff was lovely, our room was even ready early, which was a huge help. The restaurant staff and hotel staff were super friendly and kind, and the property was a good value and nice and clean.
