No, the lawyers are serious about Disney's potential liability if a non-employee is seen as being Disney staff, and takes advantage of the implied position of trust to (for example) molest a child on Disney property.
I can see the liability part, but it’s also about protecting their characters.
One fellow in Edmonton, Alberta, which is about 2,000 miles away from Disneyland was forced to repaint his garage door because he did a Disney Montage on it.
I am sure that is part of it too. I just find the whole thing hilarious, and here I am tonight within a stone’s throw of The Rat and his hole...:)
The cops must be awful busy on homo open house days.
