Hi there, Jessica!
Congratulations on receiving such a
Special Offer from Disney before it's been released to the public! Whenever I've gotten one in the past, I've squealed with delight because of the terrific advantage you have in booking exactly what you want, especially since your dates are flexible! Woo Hoo! :)
I don't see anything specific that would make the offer not include certain dates, but you can't always tell what Mickey Mouse might be up to! He's always planning special things so be sure to keep an eye out on the
Disney Parks Blog for any announcements that could be made. I would absolutely take advantage of that Free Dining offer in December though, that doesn't happen very often!
I'm sorry I don't have a more specific answer, but I hope this helps! Thanks for stopping by the Moms Panel and please let us know if we can answer any other questions you think of!
Wishing you Pixie Dusted vacation planning!
