MYW Tickets Upgrade question

[Olga]

We've bought our MYW package (for late September trip) in advance before the August price increase and changes. Thus, as I understand, our 10-days MYW (plus Water park etc.) tickets will include 6 visits. Can we upgrade these tickets to the new ones that include 10 vivsits. If yes, whether it's reasonable?

I don't think you'll be able to upgrade the tickets, but if you are able to, you'll likely have to pay the difference between what you paid and what the tickets cost now.
