HI All, I can't find this answer in the Universal FAQ so I'll just ask here. We got the Harry Potter Celebrations package and it comes with 3 base tickets for each of us. HOwever I'm wondering if there is a way to upgrade to "park to park"? (I think thats what it is called) Like Disney is there a way to upgrade at the park or are we just out of luck? (I don't think we were given the choice of upgrading, I can't remember) Thanks!
