Nice but will not stay again because of all the extra money

Liked:It was very clean and staff was friendly.
Disliked:Was very unhappy with the parking. I already paid a good amount for the room for 1 night and then had to pay to park . I can see if I was there for a few nights but for 1 night at $30 and my car next parking lot over from the hotel or pay $38.00 for valet parking. Was not happy about that . Then another $75.00 deposit . So a total of $105.00 extra after you get there . I was not happy about that .

Would stay here again.

Liked:Front desk staff was amazing! I wish I could remember her name, but one woman in particular took extra time to be kind to my daughter and talk to her about her dance competition. She went out of her way to be kind and helpful during our stay!
