Upgrading tickets - possible?

[disney-super-mom]

We bought our vacation package through DL, but now I'm thinking we should have ordered 5-day park hopper tickets instead of 4-day park hopper tickets.

If we wanted to upgrade our tickets from 4-day hoppers to 5-day hoppers, can we do that when we get there, and if so, where do we do that - at a ticket booth?

Thanks.

Yes, you would upgrade at any ticket booth - but be warned, a five-day hopper pass is $209 per person. So you'd most likely be paying an additional $40, $50 or $60 each for that extra day.
Can you try to upgrade through wherever you bought the package? I'm pretty sure it's cheaper in advance.
