I have a friend that just returned and thought this might be some funny information to share, as well as making a good topic of conversation for others to share as well.
Friend had 3 yr old on first trip, they started day 1 with a character breakfast at Chef Mickey's, anyways when Pluto came to the table (3yr olds first encounter ever with a character) she gave Pluto a hug and asked Pluto if he had been nutered

Then asked her mommy about the other characters as she noticed none of the "boy" ones had pee pees so how do they go to the bathroom
I am still waiting to find out how she explained this to her DD.
