Adding days to 1-day ticket

[g-dad66]

We have a pair of unused 1-day Park-to-Park tickets which we purchased from Undercover Tourist in 2015.

We are planning a 3-day trip in January.

Can we upgrade those 1-day tickets to 3-days at a ticket booth on our first day? Can it be either before or after entering the park?

Or is there a way to upgrade in advance?

Enter the park with the one day ticket
Go to first service and upgrade to a three day passSend UO guest service now and ask them if you can upgrade tickets prior

Issue you will have in upgrading prior to the trip is the ticket was not bought from UO but a third party vendor

If you wait until you use it, you should be credited gate value for the ticket. If you upgrade it before you use it, you'll be issued the amount that you paid for it.
