If we get Cinderella, Ariel, Aurora, Snow White, and Belle all in one event, we can finish our meal, walk out of the restaurant, leave Epcot, and hop on a plane back to Philadelphia since we'll have accomplished our goal
Last year, the goal was to meet all of the Sensational Six. Daisy was the hardest to find, but we did on the last day, and felt like we accomplished something. This year, it's princesses. We'll still need to find Tiana, Jasmine, and Mulan (she said she doesn't need to meet Pocohontas, and I don't know -- is Rapunzel anywhere?).
Maybe each time we go, we'll make it a different character theme... Villains, Pixar characters, pre-1950 characters, etc.
