You can call and request a replacement set, or you can simply cross out Boardwalk with a Magic Marker and write Animal Kingdom, being SURE not to mark over the bar code at all. That's what will be used to actually route your luggage - the bar code on your vouchers match the bar code on your luggage tags. When you check in and tell the CM what resort you're going to, the luggage with the matching bar code will be linked to you and sent to your right resort.
