I've been curious just how much Cast Members actually "know" about "insider information"/rumors. Does Disney seed info or send memo's to CM in hopes they leak to guests what they want? Or are they actually in legit meetings getting the real scoop (if so, are they required to sign confidentiality agreements)? I've read many times on the boards something along the lines of "....I overheard a cast member tell someone that...." - so I'm curious if Cast Members are a serious and creditable source, if so, how?
