If you go to guest services you can ask for an anniversary button/pin. It has Bride & Groom M&M on it . They also have to purchase a few Wedding pins, but they don't have Happy Anniversary on them.
Hubby and I collect the wedding/honeymoon pins, and have special lanyards to wear them on that were made by arizonajeff on these boards. We wear them every year at WDW to celebrate our wedding anniversary.
