Last July we took a similar trip. Starting in Ohio we headed straight up 75 to Mackinaw City and stayed at Mackinac Mill Creek Campground. Being the day after the fourth when we rolled in the place was packed and the sites are small. I couldn't open my awning but the view of the bridge and lake was worth the cramped site. We then headed down through Petoskey to Traverse City where we stayed at Holiday Park Campground. Visited Sleeping Bear Dunes which was about a 45 min drive from Traverse City. They were also having the Cherry festival which was fun as well. Go visit Rennie Orchards and pick some cherries while you are at it. When we left there we headed south to Ypsilanti and stayed at the Detroit Greenfield RV Park where we stayed a couple days and went to Greenfield Village and The Henry Ford Museum which were really cool.
