When my family and I went back in May 2000, the kids had decided on a late dinner in Cindy's castle and by the time we got out no one was in the park, so we took some awesome photos in front of the castle all lit up! It was me and my two sisters, and my sister's friend that was a current cast member there. My sister and that friend were roommates while doing the college program a year earlier and had both worked at WDW. So I was taking photos while all three of them were building a cheerleading pyramid in front of the castle! It was pretty cool.
On a different subject, I do remember during this same trip, my sister taking me to the "hidden" cafeteria in MGM where she used to work in the college program. We were over by the animation tour waiting in line and we were thirsty and she still had her ID card (up to date), so she said, come with me and act like you have seen this place before and know what it looks like. She took me on a path that I would had never seen if she hadn't pointed it out to me, it's amazing how well that hide that stuff. We went into the cafeteria and I couldn't believe my eyes, there was a Peter Pan and Cinderella all dressed up and having lunch and one of them was on the phone. It was crazy. My sister got our drinks at a cheap cast member discount and said, "stop staring or they will know you don't belong!" It was pretty cool.
On the same trip we all as a family got to go behind the scenes at Epcot when they had a store for cast members. I can't remember how we got there, but it was behind test track, because I remember seeing all the construction for building that ride next to the building. They had all this broken or returned merchandise that they let cast members buy at a cheaper price, and a little room with a TV that cast members went to to relax, like a lounge, it was pretty cool place!
Luckily my sister still keeps in touch with all five roommates and fellow castmembers, since two of them still work there and we see them everytime we go. Unfortunately since one of them worked in the Hunchback show, she's now doing a different character.
