By 1984, Epcot already had a total of 9 attractions including Audio-Animatronics.
1) Spaceship Earth
2) Universe of Energy
3) World of Motion
5) Journey into Imagination
6) Listen to the Land
7) The American Adventure
8) El Rio de Tiempo
9) Kitchen Kabaret
and i believe some minor ones in Communicore
It must have been so expensive to have so many attractions with large amounts of AA's.
How many A-A's did Epcot have total with all these attractions back in the first couple of years?
