Though, I think my grandfather really wanted to do Disney that way, they lived in Lady Lake, so it was too close of a drive. He kept hinting at it though, and we finally did a camping style trip across TN, doing the Blue Ridge Mountains.
And it drove me crazy, as it's basically a huge Chuck E Cheese with many of the same games and to see down games, all I wanted was a GEM key to fix them (normally it's a fairly quick thing to get them back online)...
This trip, we'll be back for the first time in years. I'm making sure we do a few hours at DQ, as I want to see where it sits.
