I don't know about the dinner, but we did an 8:05 breakfast, and it was great. The food was good, the kids LOVED seeing the characters, and it is awesome walking down Main Street with only a few other people around. We were able to get some great pictures of Main Street, and the castle before our breakfast, and then went from breakfast straight into the park which had just opened, and we missed all that madness at the front of the park.
