Strange question. I've got the Disney Visa so I'll link that to my account, but I've also got some Disney gift cards that I would like to add to my on board account. I know to get the Disney Visa discount you have to pay for it with the Disney Visa, but if I have both forms of payment linked to my account and I make both discounted and non-discounted purchases on board how does that work? Will Disney put the items that don't qualify for a discount on the gift cards and the ones that do on the Visa?
