FWIW, Disney was offering Free Dining or other promotions for the off-peak travel periods even when the economy was roaring good. It's a way to fill their rooms when demand is traditionally soft.
They may still offer decent promotions in the coming years, but look for the time frame to be shortened to only the most off-peak travel dates, for example Free Dining or room discounts in September when most people don't usually travel, but not In October when the weather is better, schools have breaks or long weekends, and the F & W draws people.
