I always see people walking around wearing the different buttons with what they are celebrating while at Disney. My question is, are there any perks to wearing these buttons? I see they have a "First Visit" button. This trip is going to be my 5 year old's first visit, and really my 8 year old's (she was 2 1/2 last time we were there). This is also going to be their Christmas present. Do they make a Christmas Button? Reading online, I see that we just ask a cast member for the button?
