We live in Makanda just south of Carbondale IL and directly on the eclipse (Aug. 2017) path. If you still want to stay in this area "Overland" you might want to check with Blue Sky Winery and Vineyard in Makanda, they were supposedly opening up some area on the vineyard for RVs for the event. If you decide to keep your reservations at LBL and are looking for somewhere to view the eclipse a lot of the wineries in the area are holding events that day. You can check the website of the Shawnee Hills Wine Trail for more information. Southern Illinois University in Carbondale will also be holding some viewing events that day. Let me know if you have any other questions!
We are planning a trip to Merlefest in North Carolina the end of April, hoping to go to the rally in May, spending the month of July in southern Michigan in Buchanon at Fuller Campground on Clear Lake and haven't made fall plans yet. Also planning to do a lot of weekend camping in parks in southern Illinois and the Kentucky Land between the Lakes area.
