Closest hotel is Comfort Inn in Plainwell, about 5 minutes south. Otherwise your going to have to be Kalamazoo or Grand Rapids area. Anything on West Main/M43 in Kalamazoo is about 30 minute easy drive south. Many hotels here. The Grand Rapids, north direction, best exits to get is 68th or 54th streets as they are about 30min from track and avoid some construction that way.
Let me know if I can be of any help? I live 5 min from the track and know some of the local places.
