For another Air & Space option if you like that, go to the Pensacola Naval Air Station and time it for when they Blue Angels are practicing. The practice sessions are free and there is a great museum on base that if free as well. We stayed at Fort Pickens Campground on the barrier island which is a nice and low cost national park. Fort Pickens is an interesting visit as well as it is a large coastal fort that you can tour most of and would be fairly accessible.

If you hit the Corvette museum, check into the accessibility of Mammoth Cave as I believe a couple of the tours are moderately accessible depending on your abilities/limitations. Also look into Cumberland Falls if you are in that area.
