Upgrading universal ticket after return?

[wez]

I’m guessing the answer is probably no, but worth a check. I visited universal on a 3 Park 14 day ticket in March. I might be going back on an unexpected trip at the end of the year. Is there a way to retrospectively upgrade the ticket to an annual pass?

as you guessed, the answer is no. You need to do whilst ticket is still valid as you are just changing it to an annual pass

As above, it needs to be upgraded during your 14 days- nice try though
