I saw them on Saturday on the Streets of America. I'm trying to remember what time it was. My sister and I waited, then as they came down the street, it was total chaos.
Unlike other character meet n greets, the CMs (there were 3 or 4) did not even try to start a line, and there were a ton of people literally on the cars when my sister and I tried to take pictures. It was total chaos.
Later that day, we were walking by the GMR and saw them by the hat like the "normal" characters, also with the "normal" lines. We were a bit annoyed, since we didn't see that one in the times guide. We would have liked to have gotten a "real" picture, like the ones I've seen from some folks here on the DIS.
