3. You’ve got to keep quiet.
This is two-fold.
First, if you are not a face character (you wear a costume, i.e., Mickey, Minnie, Goofy, Donald, etc.), you cannot speak—no matter what. That’s so that Guests won’t hear differing voices among the different Mickeys or Minnies or Donalds that they meet. It is also because not everyone can mimic the characters’ voices exactly, and again, the goal is to keep the Magic alive.
Second, you have to keep quiet about the role you’re playing. Outside of the parks, you are not to discuss in person, via social media or in any other manner, which character you are portraying in the parks.
