There's a DISer, jdads2 (I think), and his wife got to do it. Now, it's been a long time since I read his trip report but I think he just happened to strike up a conversation with a CM in the park that morning and was asked. I think, (jdads2, if I'm remembering this wrong, forgive me.) that the CM was dressed in more of a management attire. I don't think it was like a CM at the hot dog stand or anything.LOL
I know the first year I took my DGD to MK we arrived WAY EARLY, like the first ones there, because I went by the unoffical guide and thought since it was spring break, they might open the park earlier than posted. The park didn't open any earlier, but a CM in a shirt/tie asked my DGD if she would open MK that day. Boy was that special!
So, if I were you. I'll just sort of look around and if you see a CM that looks/dressed more "management" you might strike up a conversation & be friendly, etc. You never know, some magic just might come your way!
Let us know! Have a good trip!
