Hi Davina,
Welcome to the Disney Parks Moms Panel and thank you for asking us a question!
From what I understand about the special
Disney 14-Day Ultimate Ticket for UK Guests, you should be able to upgrade those to
Annual Passes once you arrive at Walt Disney World Resort. That being said, if you purchased your Theme Park Tickets at a discount or as part of a special offer, the value put towards your Annual Pass (and the amount of extra money you’ll need to spend on your upgrade) might vary.
Based on my past experience with converting “international” Theme Park Tickets, you’ll likely be able to put the monetary value of what you paid for your tickets towards the Annual Pass that you’ve chosen to purchase, and then pay the difference between that value and the cost of the Annual Pass.
Please note that this conversion can’t be done at a Walt Disney World Resort hotel but will need to be done at
Guest Relations at any Theme Park or Disney Springs location.
Have a Magical Day,
Lynne
