Hi Kristen,
Thanks so much for visiting the Disney Parks Moms Panel with your question.
My family purchased Annual Passes through Disney Vacation Club, and we were able to link them to our MagicBands through My Disney Experience with no problem. I also called and spoke with a cast member who let me know that you should also be able to link any Disney theme park tickets that you purchase at your local Disney Store to My Disney Experience.
To link any Disney theme park ticket, make yourself an account at the
My Disney Experience website. From there, you can click the icon to "Link Existing Reservations and Tickets," which will take you through the process of linking your tickets. If you encounter any issues, you can call 407-939-7849 for help. If you purchase the tickets through Disney Vacation Club, you can also call Disney Vacation Club Member Services at 1-800-800-9800. There is now a menu option for assistance with MyMagic+, which includes My Disney Experience and MagicBands, early on in the menu options.
I hope that this information is helpful for you, Kristen! Have a wonderful time planning your vacation, and please do not hesitate to ask if you have any further questions.
