We're heading to WDW from the Chicago area for T'giving week. We'll probably leave at about 1:00 on the Friday before Thanksgiving and drive 9-10 hours, then do the rest on Saturday. We usually end up stopping late at night after campground offices have closed and when rest stops and Flying J parking areas are full. Does anyone know of a good place to stop that's roughly halfway between Chicago and WDW? Either a campground that's open late, a WalMart or equivalent or a rest area that doesn't fill up? We have a MH with a generator so we don't need any hookups - just a place to stop and catch some sleep.
