Sorry for all the questions.
We will be in the World for 5 days, and 2 of those we are planning on Universal. If we end up only wanting to be in Universal for the one day (we have never been there) and wanted to add a day to our Disney vaycay, would we be able to just get one day tickets somewhere? How would we do that? (Yes, we’d be eating a day of Universal admission and also wouldn’t have FPP (although I do have a lunch res in case!) but I’d rather that then be somewhere I don’t want to be.)
You should be able to add an extra day to your existing Disney ticket if you want and just pay the ticket price difference. The KEY, however, is that you have to make the upgrade BEFORE your final admission.
In other words, if you have 3 day tickets, and you have already used all three days, you can’t then add a day four. But if you have 3 day tickets and are on day 2, you can add a fourth day, etc.
Here is Disney’s official answer:

thanks!
I think that you will enjoy Universal. There is plenty to keep you busy for two days.
