We have purchased seven day tickets for the four of us for our trip next October. We have them in the form of printed vouchers as purchased online from Viator.
We have sinced booked another short trip for February and would like to visit UO/IOA then as well but don't know whether it would be possible to upgrade to annual passes from these tickets? Also any idea whether we could do this in advance, maybe over the phone with Universal?
If we were to do it in the parks would we have to upgrade before using the tickets for the first time?
Also not sure how much credit we would get toward the annual passes, does anyone know how this is calculated please? We paid $ 364 total for the four back in July this year.
Sorry for so many questions but I seem to have messed up by buying the wrong passes in advance
Thanks for any advice!!
