I brought lanyards with the intention of putting holes in the cards and putting them on the rings. The CM at guest services said that they did not recommend putting a hole in the KTTW card because it sometimes made it difficult to swipe correctly, so we just carried it around in pockets. I would have used lanyards if they had a pocket for the card. I kept ds-8's card, but the two 12yo kept theirs. The 8yo liked for me to give it to him so he could open the room.
