Hi Patricia,
Welcome to the Disney Parks Moms Panel and thank you for your question! I am so glad you were able to take advantage of the Free Dining promotion in the past.
Fall promotions have not yet been announced, so there is no guarantee that a free dining promotion will be offered this year. In the past, announcements have been made in early summer so I would keep an eye on the
Special Offers page to get the most up-to-date information.
There are typically some Disney Resort hotels that are not included in this promotion, but again it's not something we will know until an official announcement is made. If you would like to see historical information on what was offered in past years, I've found that MouseSavers.com has a comprehensive list.
I hope you find an awesome deal for your magical fall vacation, Patricia! Hope to see you real soon.
Andrea U.
