Here's one the children will avoid for different reasons. Dressing up as a Disney character and walking around the park should be a fun and exciting adventure - meeting family, making children smile, signing "autographs".
However, the poor sap who has to dress up as Jar Jar Binks will most certainly be miserable since no one really likes him.
Seeing him walk around Disney World will probably cause people to spontaneously throw their turkey legs and popcorn at him. On the plus side, if, for some reason, you DO want a picture with him, there will never be a wait.
