What fun. I remember Six Gun Territory well. Fake western town, fake gunfights. The day we went back in the mid-60's, a teenage Ron Howard was there signing autographs and fake gunfighting.
Rainbow Springs - not just a glass bottomed boat. You sat underwater entirely...kind of like inside an aquarium with the fish outside. And there was a place where screens were draped over the trees and exotic birds were within.
Cypress Gardens - water ski shows
Bok Singing Tower in Lake Wales - bell concerts several times a day. Nearby is/was a hill where you could put your car in neutral, and it appeared to roll uphill. I forgot what it was called.
