I'm curious... how do the Cast Members know when it's your birthday? I hear them tell people happy birthday using their first name but how do they do it? My boyfriend thinks they have a button of some sort that prompts this to happen, but I don't know. I went in for my birthday yesterday and when I was admitted into the park the lady checking tickets told me happy birthday, but that was it for the rest of the day. I didn't get any such button if that's the way it's supposed to work.
