You can purchase Sorcerer Pass “vouchers” any time now, and they can be activated when you visit WDW in January. The one year of use will not begin until you use them for the first time to activate them. For Sorcerers purchased through
DVC, they should be linkable to your My Disney Experience accounts in advance of your visit, and also may activate when you first tap in at one of the park gates. However, it sometimes requires a visit to Guest Relations at the park entrance to activate, if proof of eligibility to purchase Sorcerers needs verification. (When we did ours in April 2023, purchased through DVC Member Services, verification was done over the phone at the time of purchase, so they activated when we first visited. We let those expire this past spring and purchased new vouchers online that we will activate during our next visit in January. We expect to have to confirm eligibility in order to activate these.)
