Reporting a newbie mistake so other don't make it. I saved up about $700 in discounted GCs. Around day 5 of our 7 day trip I went to front desk and had them apply the gift card to my folio. She did and handed the GC back to me (but I can't find it). WDW had issues with end of trip folios going out to people last weekend and I called today to get it emailed to me. When I reviewed it there was only a random $63.17 credit to my folio from the gift card. Everything else went to my CC. HUH...makes no sense.
I then when online to check my GC balance - yep still over $600 on it.
What happened was Disney had just swept my folio balance over to my credit card mid stay. So, when the CM applied my gift card, my balance at the time was only $63.17. Thus that is all they took from the gift card.
I haven't decided yet if I will call and see if they can reverse the credit card charges and apply the gift card instead. Seems like a hassle.
BUT........What I am most thankful for at this moment is that you all taught me how to register my GCs and consolidate them on the DGC site. If I hadn't done that and I never find that GC then I would have really been SOL. At least now I can just go buy a small one somewhere and transfer that balance to it. Thank you for teaching me that trick!
