I emailed WDW, and this was the official response:
"Dear Danielle,
Thank you for contacting the Walt Disney World® Resort. We are happy to
know you will be vacationing with us and experiencing the magic!
You will be happy to know that you may use table service meal
entitlements for quick service meals, but you cannot use quick service
meal entitlements for table service meal experiences.

While we sincerely appreciate your interest, this electronic mail
department does not have access to the Dining System. For all questions
regarding dining reservations, it will be necessary to contact the Walt
Disney World Dining Department directly at 407-WDW-DINE (407-939-3463).
To avoid any cancellation fees, we urge you to call to cancel any dining
reservations.
Danielle, we look forward to creating lasting memories and magical
experiences during your visit to the Walt Disney World Resort!
If you have questions or need further assistance, feel free to contact
us.
Please include your full name, E-Mail address, and reservation number if
applicable on all correspondence.
Sincerely,
