When we went in 2009, there was the Disney Junior live show as already mentionned. These were more like puppets and no meet and greet. However, during the Trick or Treat party, we saw Annie and June from the Little Einsteins and they were out meeting guests. I think Handy Manny was there too. They may have even had scheduled times during the party as it was near the Hollywood backlot and I remember waiting because we knew they would be coming.
