Hi, Dara!
This is one of those "grey area" questions that demonstrates the incredible amount of information available to Disney vacationers out there.
Curious about this myself, I called (407) W-DISNEY to get the scoop.
This particular policy is not widely known by Cast Members, and, while it does exist, you may need to be extra-patient and diligent in your efforts to acquire your tickets early.
First of all, you must be staying on property, and the Resort you're in early needs to be the same Resort attached to your
Magic Your Way package. If both of these conditions are met, you may arrange to pickup your tickets
no earlier than three days prior to your package start date. You will need to pick them up at a Guest Relations window or at the Concierge desk of your home Resort.
Again, this is not a widely-advertised policy, so please do not become frustrated if your Cast member does not immediately know that this option is available to Guests. You might need to pursue a couple of Cast Members before you can successfully have that policy invoked.
Have a great trip!
See you later, celebrator,
