Shoot - that's what I get for not dropping in more often.
I did Lunch with an Imagineer a few years ago with my SIL - she wanted (and still does) to be an Imagineer at some point. The two of us, and several other people, all got to eat with the Imagineer in a private room in the Brown Derby, so we actually had a chance to ask questions.
Now, he would not answer any direct question - asking "Are they going to be making a ride based on Incredibles?" was doomed to get an evasive answer. But asking about the Imagineering process, what kind of things they do, biggest challenge - those were all fair game.
It was fun. I'd like to do it again sometime.
