I get your point. It isn't so much about what happens in the episode, it more that if you're a "friend of.." one of the characters, you need to refer to yourself as such or get in trouble, but Disney can put that on TV and get away with it.
My kid watches Good Luck Charlie on the Disney Channel from time to time, and there was an entire story arc where Teddy and her friends were "friends of..." characters at 'Super Funland.' While it wasn't WDW or DL, I don't get why it was okay to show this to kids on the Disney Channel of all places.
