Too bad they closed "Wally World" (or "America's Favorite Family Fun Park") after the Griswolds had their little "incident" otherwise that would be a good place to unwind.
Seriously, it sounds like it will be an "epic" road trip. I'd be up for a drive like that; but the wife, not so much
. She prefers the luxury of getting there in a few hours; not weeks. I'd be like
and would have the time of my life.
Good luck with your plans and keep us posted...
