Not really.
The anecdotal stories told to me would indicate that the ratio was fairly close.
Problem was that parents "expected" the kids to be scared of the coasters, especially Space, so we're less prone to pressure them to ride.
Despite the numerous warnings, they were "surprised" by AE because they didn't expect a show to get the same reaction.
The kid cries...mom and dad are ticked off/feeling guilty for taking them into the show...so they complained.
Also, do not underestimate the power of the plush in this situation. It was a HUGE contributing factor.
Had Stitch, who was very popular at the time and guaranteed an increase in merchandise sales, not been available...AE would have remained much longer. (It wasn't as if there were so many complaints that they would have closed the show and left the space dormant.)
They probably sold enough Stitch merch in a week to offset the tiny budget they gave Kevin Rafferty to convert the show...
But, anyway....back to Guardians at Epcot. Boooooo!
