CHOC Walk Help: I didn't have time to "check in" and today is the last day to do so at Irvine by 3pm so I can pick up my shirt and wristband for the event. Does anyone know if there is another way to check in, maybe at disneyland tomorrow before the ceremony? I was looking for the answer at the CHOC walk site and didn't see anything about it. Can somebody who's participated in the past know if I can check in at the park instead? TIA!
