Sunday was a much less busy day than Friday and Saturday had been, at least in the various sessions. I don't think any of them filled up - I know for a fact that the two Arena presentations and all of the Imagineering sessions still had room for people to walk in. The exhibit floor was busy, but not as crowded as Saturday. I had a chance to go through the new Tomorrowland exhibit, which had opened the previous afternoon. It contains "artifacts" from the supposed "1952" box. Bizarre, and since I didn't see the Disney Studios presentation I didn't really get it.
