OMG this is us exactly!!! I have never paid our trip in gift cards and I thought the same thing, i'll get gift cards from Target and save the money. and now it looks like we are going to wind up cancelling. So I asked our travel agent how this works, because we gave her one card and just kept feeding money to that card . ($5300 total so far) SO she told me that Disney will refund the whole thing to that card, HOWEVER , one card will only load $1000 at a time. So what I have to do is keep tabs on that card (on the gift card site) .....when Disney refunds the first $1000, I have to pull it off that card to another one. Then DIsney automatically refunds the next $1000, I pull that off and put it on another gift card....and so on until our $5300 was refunded. who knew it was going to be this huge a hassle. Although I'm just glad we'll get the entire thing back.
The way we're looking at it is that our 2021 trip will be paid for, so that's awesome..... while we may not be able to go this year, we will try for next year for sure. And who knows, maybe we can ride Tron, Ratatouille, eat at Space 220......
(I'm trying to stay positive......)
