I was chaperoning a group of cheerleaders in March (including two of my dds). We had four day convention tickets and with our cheer schedule actually only got in the parks twice. The group of girls decided they would keep their hoppers to scrapbook (these hoppers have expiration dates). After talking to them about random acts of kindness (not legal to give away convention tickets I know) they decided to make disney more special for someone else. They all went over to Animal Kingdom and gave their hoppers away outside of the park. It was quite a spectacle and the girls still talk about it as a highlight of their trip.
Before we did this, guest services was kind enough to photocopy the passes for the girls to scrapbook.
