Visit Kermit Weeks' museum at Polk City, off Highway 4 between Orlando and Lakeland, west of Kissimmee and just north of Jack Brown's at Winter Haven. Think you can get rides there, but the musuem is well, well worth a visit. Sunderland, Connie, B-24, etc, etc, etc...
Kissimmee has a Waco - last time I was there it was being put back together after a unscheduled entrance at Disneywotsit.
If you happen to go down to Key West, there is a Waco joy riding outfit there, and I think you might al;so be able to get rides in Cessna Floatplanes - dolphin spotting?
Also a museum at Tamiami. what about a ride in a Chalks Mallard from Watson Island, Miami, out to Bahamas and back.
Enjoy your trip!
