Hi Marco,
Welcome to the Disney Parks Moms Panel and thank you for asking us a question, my fellow Canadian!
The ability to add extra options to the
Theme Park Tickets you’ve already purchased depends on several factors, including how you purchased them. For example, if you purchased your party’s tickets using the (sadly, now expired)
Special Offer for Canadian Residents, based on my experience, you can upgrade them to add the Park Hopper Option at
Guest Relations at any Theme Park, but you’ll need to pay the difference between your purchase price and what the equivalent full-price ticket would cost at the time of your upgrade.
If you want to get more concrete information about what your options are and how much they might cost when you start your vacation, I’d highly recommend
contacting Walt Disney World Resort. Please have your purchase’s confirmation number handy and they’ll be more than happy to help you “untangle” your vacation plans!
I hope my answer helps you plan your upcoming vacation. Please don’t hesitate to come back and see us if you have any other questions.
Have a Magical Day,
Lynne
