Disney is VERY protective its trademarks, especially its classic characters.
I would not want someone impersonating my characters since I would have no control on how said impersonator would act.
If they got a fast Pass for the park that is a freaking golden ticket (you usually can only have one at any given moment and have to wait).
Likewise shorts and short for 2 at Disney about $100+
They should be grateful.
Peter Pan was published in 1906. There is no copyright on the character, and you can't trademark tinkerbell.
