Upgrading child's ticket to adult when FP+ is involved?

[Jedimom]

I purchased 4 adult and 1 child 5-day MYW tickets in January from UT. At the time, I thought we'd be back to Disney while my youngest was still a child. That may or may not be the case anymore. If I can manage a trip to FL by Jan 2016, we intend on doing Universal & Sea World, and maybe one day at Disney (undecided). In that case, when we next return to do Disney she will be 10 and will need an adult ticket. I know you can upgrade at the park....but I would think if that's the case, then I should probably bring her ticket with when we go to Florida in Jan 2016 and upgrade it then? Because otherwise won't I have trouble linking her ticket to the whole FP+ system, seeing as how her age and ticket won't match? Or won't that be an issue -- can I still link her and obtain FP+, then upgrade at the park when we get there?

Also, where can I do the upgrade? If we end up not doing a day at Disney.....is there a place in Downtown Disney which'll allow me to upgrade her ticket?

Thanks in advance!!

1. Correct.
2. Meh. Small possibility of "issues." If you can avoid them in advance, that's fine.
3. You can. It will just take an extra trip to a ticket booth or Guest Relations for the (difference charge) upgrade.
4. DTD has two Guest Relations. One in Marketplace, one on the West Side.
You can go to either.
