But, I don't think it matters your limit for you to be able to use the codes they release. But, you do have to pay with the disney visa card and I think a package has to be paid off 45 prior to arrival so you'd end up needing a higher credit line than 600.00.
I applied for the card last week, in hopes to get the visa discount, however, my trip is already paid off. Does this mean, I would have to have them refund the entire trip and then recharge it on the Disney Visa to get the discount?
