That is the best place to see Belle... She signs autographs and takes pictures with those guests that were there for the show. It is really a quaint experience. People will try and get into the area after the show just for photos but the greeters are really good about turning them away. The experience is really reserved for those that are there for the show itself. Check the times guide when you arrive, but they usually have the show at:
9:10, 10:10, 11:10AM, 12:10, 2:10, 3:10PM
