Others, like Hoon Lee, turned out the other way and congregated in huddles to chat with each other and fans, which was really cool cuz it gave it a relaxed atmosphere, but made it awkward for me as I had to interrupt them for autographs.
The little princes and princesses came out in a huge gaggle and promptly left without doing any SD activity (they're so cute!).
FYI I went during a Sunday matinee during the fall, probably waited around 15-20 min and it wasn't particularly crowded."
The mom of one of the Matildas told us once that the children are not allowed to sign. Apparently they are allowed to chatter on about their plans for Easter, though, because that's what happened with us (Matilda quickly bonded with my then 12-year-old daughter). It was pretty adorable.
