My hubby took the kids to try to see them with limited time, and went through the animation show by mistake. They enjoyed the show, but then didn't have time to see the incredibles (I was saving seats in the last Beauty and Beast show). We went back and cut through the gift shop. The line was pretty long, but certainly worth the wait. My kids enjoyed seeing characters more than almost anything (except Space Mountain and Rock n Roller coaster!)
We saw Mr. Incredible and Elastigirl. They thought that was awesome!
