@Prince Thomas ? I was there and saw it all. Horizons, Spaceship Earth Mk. 1 with Vic Perrin, Communicore with glass walls looking out onto ponds and greenery, UoE with the Radok panels, "Coming Soon" signs for Israel, Africa, etc., the rainbow tunnel upstairs in Journey Into Imagination, "Listen to the Land," double-decker buses circling the World Showcase promenade, Laserphonic Fantasy, The Bird and the Robot...
We shall never see the like again.
But yes, HMF, it's great that threads like this allow people who started going more recently to understand what it is they missed. Although I saw almost everything that ever was at WDW, I wish I could go back in time and visit Disneyland when it was still at the stage that things were being added and not replaced.
