We have AP's that have already been activated. We bought our daughter the child one, as she was 9 years old during the trip that we activated it. She will be turning 10 before our next trip. Do we need to do anything about this? I read somewhere that either Disney or Universal let you exchange it for the adult one without charge, but I'd rather not swap it if I don't have to - as then she'll have to do the fingerprint and that slows us down. (I had trouble with my fingerprint several times on our last trip when we did Hogwarts Express, so t could potentially slow us down more than expected).
