I have my Disney packaged paid in full. When I booked the package I only had them put 2 day base tickets on, as I was not sure of the exact number of days I would need. Well, now I know, and I would like to change my tickets to the ones we will actually use. Is it too late to do that? I am 60 days out from my trip, if that makes a difference. I would just like to get the tickets set and paid for so I don't have to fuss around with them at the parks.
