We are a family of 2 adults and 2 boys, ages 5 and 7, who will be travelling up the shore of Lake Michigan on Michigan's west coast and hitting all the beach towns on our way to the upper pennisula. We have found so many things to do along the way, we would like to "wing it" and not have set hotel reservations. Is this a realistic plan in mid to late July? Will we be able to find accomodations along the way or is everything filled up at that time of year? We are willing to stay at mom and pop motels, hotels, resorts or a cabin as long as they are clean and safe. Can anyone give us advice on this and also any recommendations on where to stay and what to do. Thanks in advance. We can't wait to visit Michigan!
