I was hoping someone might know the answer to this: We were supposed to go to Disneyland in June, but 2 days before the trip I had to be hospitalized. We had bought all out tickets beforehand. Now we are going in January (yay!) But now my oldest daughter is 10 instead of 9. We have a child ticket (6 day hopper) for her, can I apply that toward an adult ticket? I obviously want to do the right thing and buy her an adult ticket, but not if that means I completely lose the $ we spent on the child ticket. Thanks.
