Can I upgrade just ONE base ticket upon check in with the MYW + Free DDP?

[wdwobsessed]

Taking my niece this time and my family has 4 days left on our hoppers from last time. What I would like to do is upgrade just her 1 day ticket.

Knew I could not do this in advance - but can I do it upon check in or at guest services.

Or would I HAVE to upgrade them ALL?

Thanks

everyone will have their ticket on their own KTTW card and you can upgrade 1 or all.

Your choice.
