Big 80-day Spring Road Trip From Spokane, WA to Orlando and Back

[the5reeds]

We're schedule to depart on a 8200mi 73+ day RV road trip in early April. We're starting and stopping near Spokane WA. Aside from necessary over night stopovers and compulsory visits at various relatives in CA, we plan to stop at the following locations; Bodega Bay, Lake Havasu city, AZ, Petrified Forest NP, Santa Fe, NM, Carlsbad Caverns, NM, Austin, TX, Beaux Bridge, LA, Mandeville, LA, St. Andrews ST PK, FL, Disneyworld Fort Wilderness, St Augustine, FL, Jekyll Island, GA, Savannnah, GA, Charleston, SC, Great Smoky MT Natl Park, Cumberland Gap Natl Park, Solon, IA, Brandon, SD, Badlands NP, Custer State Park, SD, Yellowstone NP. I've attached our current route, although I haven't tweaked it for avoiding the nastiest of mountain passes (we're towing a car).

Any comments, on route suggestions, or sights?
