Yes, since you purchased tickets directly and separately from Disney, they should be able to process a refund and repurchase transaction.
Thanks, my wife is actually on the phone now trying to work through this. There's a couple other hiccups (gift card/separate credit card/transaction for one of the tickets), so we'll see how it goes. We have all the receipts and hard tickets, so.... Our biggest worry is/was losing our fp+ times. We got exactly what we wanted Tuesday morning....
I'll keep you all posted!
Edit: She got a "You have to go through
DVC" and transfer. Waiting now. I suspect DVC says "No, you need to talk to ticketing". Ugh, why is this kind of circular round and round so common with Disney?
Edit2: DVC says this transaction must be done in person. She's calling ticketing, again, to see if she can get a more knowledgeable agent. We're using the 403-939-7523 number....I'm assuming that's the correct one.
Edit3: Third CM, all say the same thing. But at least she got this one to transfer her to a "Ticket Specialist"...with appropriate 30 min hold time.
Edit4: SUCCESS!!! The secret is to ask for Ticket SERVICES, not Ticket SALES. Whatever that meant.

But we're all set!!!
