Trying to think of characters that were out for the half...
Pirates
Heroes
Villains (Evil Queen and Maleficent when I went by)
Buzz in Tomorrowland
Queen of Hearts at Teacups
Beast at Be Our Guest
Anna, Elsa and Kristoff on the castle
Woody in Frontierland
Mary Poppins Penguins near Grand Floridian
Tourist Genie at Golf Course
Coming back down World Drive, another chance at Heroes and Pirates
Mushu backstage at Epcot
Princess Daisy (!!) at Port of Entry
Characters at finish - it was Donald and Goofy for me.
I'm sure i'm forgetting some, can anyone fill in the blanks? There were a couple of guys out with a car near the Car Care Center but i'm not sure that counts...
EDIT: and the wedding pavilion guys, I always think that's a weird one.
