Does anyone know if you have to show the postcard when you check in? Is it like AAA when you have to show your card? I'm asking because the pin code I used was sent to my address but with my mum's name, but the CM said it was OK to use it, but now my DH is worried that we'll have a problem when we check in because my name is different than what's on the card. I'm thinking that they don't ask to see the card when you check in, and my ressie is showing up OK on the Disney website, so no worries. Anyone out there have any experience using these pin codes???? Thanks.
