ETA:
I ended up finding an open appointment at the Detroit (Ambassador Bridge) center so switched from DTW since it is about 20 minutes closer to home. Arrived at 10:55 for my 11:00 and was back to the car by 11:05. Most of that was walking to and from the car as a semi was blocking all of the close in parking. It is a tricky location next to the truck processing facility. You have to follow the entrance to the Ambassador Bridge and then bear left to the truck processing terminal. There is decent signage, but you do have to follow the "Exit to Canada - No Reentry" path. Leave extra time in case you get turned around.
