I did this on my solo trip a couple years ago. The experience was awesome for the most part. Only problem I had was a father & son that were there and the son hadn't been on some of the rides, Tower of Terror being the main one I remember out of quite a few, so the Imagineer refused to speak about any of the "secrets" about any of the rides the kid hadn't been on yet. I don't remember the Imagineer's name, but I remember that he mostly worked on attractions and had worked i some way on the majority of the ones that had opened in the last 10 years or so. What he would talk about was really interesting, I just wish he had been "able" to talk about more... I understand why he wouldn't, but I would have LOVED to hear about some of the little details and such about the rides.
