I had totally forgotten this happened on our trip until I read your thread, thanks for the memory!
We went to the PPP in late January, and a couple (mid to late 20's) were alone and all dressed up: he in a full pirate costume, and she totally decked out in a Tinkerbell outfit (Tink isn't really a princess either, but that's OK, she looked pretty cute!). Well, DS is 2 1/2 years old, and kept trying to jump out of his seat on the bus to get to "Dink! Dink! Dinkerbell!" all the way from POFQ. We finally got off the bus at MK, and the poor little guy took off so hard, running on his stubby little legs to get a good look at "Dink". I was even going to ask her if she could just stop and say hi to him, but they were walking too fast. Once when we were walking I looked down at him, and he wasn't there. I whip around, and there he is, takin off in the other direction, because he finally caught another glimpse of "Dink". I think the pirate was starting to get a little jealous!
