I don't remember what it used to be... but I definitely remember JII not being what it is now. But when I was little, it was something me and my sister loved... nothing about it is familiar anymore. I hoped that some of those pictures would trigger some memories, but not really. All I remember was going up in the ride and seeing Figment at some point.
Anyway. The space gets used for regular operations stuff like... you know... training and meetings and whatever. What I don't understand about the emergency exit access thing is that it doesn't HAVE to be inside the attraction. An outdoor emergency ramp exit could be added backstage, out of sight. Like an escape ladder or something... it wouldn't even have to be pretty, wouldn't cause refurb of the current location, and probably wouldn't have to be that expensive. :shrug: Why not?
But MOST OF ALL---- I wish SO MUCH that it would become the epitome of Imagination itself, and become WDW's Blue Sky Cellar....... wouldn't that be amazing??!
