Not sure if it's classed as a secret or not, but one of our great tips is to do the animation/illustration class at the end of the Art of Animation attraction. You don't have to go through the attraction, a CM will tell you times an illustrator will be there teaching you how to draw. But at the beginning of the class ask the illustrator if you can have their picture at the end of the class, they will sign it and you can take it home. We have 3 from our last trip, Disney originals! As well as our own, slightly less perfect artwork.
