Can 1 day tickets(from Ticketmania) be upgraded to 2 day ?

[mill4023]

My mom and sister got 1 day tickets from Ticketmania because they were originally just going to do 1 day at IOA. Now they'd like to spend a day each at IOA and USF. Can they upgrade their tickets at the gate or will they need to buy another full-priced 1 day ticket?

Yes, they can. It is around $45 plus tax to upgrade them to a two day/two park ticket. (There are no two day/one park tickets sold at the parks.) It is still chepaer than just buying another one day ticket. Plus with the 2 day ticket they can upgrade to the 3rd day free.
