The hotel I know the most about would be the Courtyard Auburn Hills. It is located right across from DCX HQ and the Chrysler museum in Auburn Hills. From that hotel it would be about a 10 min drive to the top of Woodward.

Zoom out three times and you will see Woodward Road to the South of the Hotel.
