Hi Jessica! Welcome to the Disney Parks Moms Panel!
I love that you are already starting to plan your next trip! If I am not at the Walt Disney World Resort, I am trying to plan for our next visit!
It has been my experience that the “One Delicious Deal Offer” or “Free Disney Dining” offer has been offered a couple of times this year. There really isn’t a guarantee however that this will be offered next year. If Disney does decide to offer this, they will have specific stipulations such as must stay seven nights and purchase a seven day Park Hopper Ticket (this is only an example, this may not actually be what the offer says.) Whether or not there is a pro-rated offer will be determined at the actual time of offer. Often these offers change each time they come out.
Whenever I am booking our vacation, I make sure to check out the
special offers portion of the website when I am booking and also even after I book. If a new offer comes out after I have already made my booking, I always
contact the Walt Disney World Resort Reservation line to see if the offer can be applied to my existing reservation.
I hope that you will get the offer that you are dreaming of! Have a magical time!
