Changing method of payment for 1 night room only

[ml123_9]

I booked a one night room only reservation with a discount at PORS for a night in August. I now have a bunch of reward points on my Disney Visa that I know we won't be able to use in our one day. So is it possible to change my payment method to the redemption card even though it's already been paid for on my Visa without losing the discount? Thanks

You're going to have to call. You essentially need them to refund your payment, which means you're canceling your reservation and making it again to make the payment in another form. If the discount is still available then it should be fine. If not, then you might be stuck.
