Everything was good. Only negative was they only had one elevator working. With mutiple events that weekend, it was frustrating sometimes waiting on it.

A 4:00 PM check-in time while pushing a $20 "early" check in time is an egregious money grab, especially when there are fewer than 10 cars in the entire parking lot when we arrived. I will no longer book your hotels if the check in time is not until 4 pm. The lobby bar and restaurant business hours were very haphazard.
