Don't forget to tell the resort, so she can have a Birthday button waiting for her. (Or ask for one at the desk). You can do the Bibbidi Bobbidi Boutique, but I don't know if there will be any in-park reservation slots yet, and I know she's not HUGE into princesses. You can arrange to have Mickey call her in the room, if you know when you'll be there. When she wears the birthday button, she'll get a lot of "Happy Birthday"s from the Cast Members.
