The main hotel has free parking at all times. However over the weekend, that space becomes very tight.
This year the office building beind the hotel has graciously offered to allow use of their parking space!
If you have any trouble finding a spot at the main hotel, from Friday, 6 PM on through the weekend additional parking is available at the lot in the map above. It's accessible from Orchard Hill Pl, which connects to both Haggerty Rd and Eight Mile.
