I will be staying with family in Green Bay and will travel one day to Manitowoc. I doubt I would make the 1:55PM ferry so would have to wait for the 12:00AM one. Is there somewhere near the ferry to spend some down time? Same thing on the other side in Ludington. I am not sure if I would travel beyond Ludington as soon as I finish the crossing, and need a place to hang out or camp.
By chance are there parks near the ferry station that one could safely catch a nap?
