Planning a trip for next summer, looking for recomendations

we went around Lake Michigan last year. I would check out the House on the Rock in Spring Green, WI., Peninsula State Park by Green Bay, WI., Munising, MI has a nice city campground where you can check out the pictured rocks and waterfalls, and Tahquamenon State Park is awesome. Wilderness State Park is close to Mackinac City, we also spend a night or two in Petoskey and also enjoy Sleeping Bear Dunes, there is also Indian Dunes State Park on the south end of Lake Michigan.
