Reservation Guarantee Question

[likesdisney]

I have a few advance dining reservations for Disney and have of course had to guarantee with a credit card (all made at the 6 month mark a little while back) But since then I've had a problem with credit card and I've had to get a replacement. Do I have to call Disney and let them know or is there a way to go on My Disney Experience and change it myself. I don't want to have to loose all my reservations which I wouldn't be able to get back at this point.

No, there's no need to update your credit card information. You won't lose the reservations.
