The 'Contact' page on the hotel's own website has a link to 'Car' which explains the parking options. (Sorry but TripAdvisor doesn't allow me to post the web link!)
The parking garage is a 10 minute walk. We were able to unload on the very narrow drive just in front of Mary K, then moved the car to the garage. Don't forget to take the parking ticket with you as it is the key to reenter to retrieve the car. I speak from personal experience. ;o
