I just stayed at the Hilton Garden Inn for $99 and it included parking & breakfast. It was fabulous. Due to a Detroit City by-law the hotels cannot allow you to park at the property for extended periods. We took our van to Quik Park and the Garden Inn gave us a card to hand it at departure. It went very smooth. We had 90 minutes for check-in and it was barely enough time ~ be sure to allow two hours even for domestic flights.
I would definitely stay there again.
