I enjoyed the stay, and the event I attended there was excellent. However, I think it is unconscionable to charge $65 to valet park when the garage is located down the street from the hotel for a cost of $6.00, but due to weather or if you are leaving in the early morning hours when it is dark and traveling alone (as was I) it is dangerous to have to enter the parking lot alone. I also thought the additional $50 early check in (I arrived at 12/check is at 2:00) was a bit unreasonable.
