Guest Services and most stores at the Disney Parks have buttons that can be personalized to say what you are celebrating and they are FREE, just ask!
Last time we went with our daughter and her fiancé, they got “just engaged” buttons! Castmembers will usually shout out a Happy Birthday or even sprinkle a little pixie dust magic if they see you wearing one. What is your favorite button to get/wear around when you are in the parks?
