Upgrading tickets

[cheeky monkey]

I am so excited to have booked our trip for April!

We have 7 day magic your way base tickets. In the event we want to go to a waterpark, Disney quest, or possibly park hop-can we upgrade our tickets at the ticket window or do we have to do it in advance?

You cna upgrade at the ticket windows or at your resort if you are staying on property:thumbsup:

If you decided you only wanted to do 1 day at a water park, it might be worth checking to see if would be less expensive to only pay the admission to the water park the day you go. That is, if you decided you didn't want all the other options you get with the Water Parks & More feature. To add the park hopping feature, you can do that ahead, or, as JPL said, at a park or at your on-property resort.
Have a wonderful time!
