Motels / hotels near Twin Cities or Stillwater, MN that take cash and no questions?

Are there any hotels or motels near Stillwater, Hudson, or the Twin Cities that will accept cash for a few hours or a night and not ask questions about things like age? It's a week til I turn 18, but i need the room this weekend for me and my friend to stop at on our way home from a trip, just to clean up etc before we go to a wedding. My house is too far to stop at beforehand.
