I never thought about this before since this is the first time we are letting the 2 older granddaughters go off alone. We have park hopper tickets and once we get into Disneyland I usually take all the tickets from the kids so they won't get lost. This year we have a 15 and a 16 year old who want to go on their own as they want to ride the larger rides. Will they need to hang onto their tickets to get into DC or does the stamp tell the CMs at DC that they have Park Hopper tickets. Thanks ahead for the info.
