Hi Lilia,
Welcome back to the Disney Parks Moms Panel and thank you for asking us another question.
The short answer to your question is "yes... and no". From what I understand, all
Special Offers, including those associated with any
Disney Visa cards from Chase, are usually limited to a certain number of reservations at each Walt Disney World Resort Hotel. While sometimes it’s possible to apply a promotional offer to an existing Magic Your Way Vacation Package, you may have to cancel your reservation and re-book it at a Resort that allows you to take advantage of the Special Offer.
You may get lucky and be able to get a package that is identical to the one you had initially booked, but there is a chance that you may not. In that case, you’ll either have to choose a different room type/Resort or you'll have to stick with your original package (and cost).
I hope my answer helps you plan your family’s vacation this March! Please don’t hesitate to come back and see us if you have any other questions.
Have a Magical Day,
Lynne
