upgrading ticket question?

[joloco]

In January we purchased 2 day 3rd day free tickets ..... We have not used tickets yet. Can you tell me if they would allow you to upgrade to the 2 park annual power pass. I know there are black out dates. Also do they have a child rate? I think the adt rate is about $99.00. Thanks.

You can upgrade any valid ticket and pay the difference.

I had the same tickets and was allowed to upgrade, but the child ticket (power pass) is the same price as the adult.
