Have to agree that the character interaction was much better at DL when we were there two weeks ago than any of the 5 trips we've taken as a family.
Some of the highlights of that trip include my DS getting to ride the train halfway around the park with Mary Poppins, Bert, and one of the penguins (he sat between Mary & Bert and even held Mary's parasol for much of the trip), Goofy sitting down next to my DS prior to the DL parade and pretending to eat his crackers and drink his water, and a ridiculously long interaction between Captain Hook, Peter Pan, Tigger, and Pooh involving sword fights, balloons, and CPR--Tigger and Pooh won!
All that said, I felt horrible for most of the characters at DL since there were very few that had any handlers keeping order. It was a free-for-all with about 1/2 of the characters we saw all week--no lines, parents pushing their kids in front of the character, etc.
