Hi Melissa! Welcome back to the Moms Panel! The
Walt Disney World special offers I mentioned in a previous answer can be found by visiting the Special Offers link on the Disney World website. I've included the link above, so you can just click that to take you to the current offers. Like I stated in my answer, there are room only and package discounts available from August 15 to Sept. 28, 2013 and free dining is available from Sept. 2 to Sept. 25, 2013.
Since you are visiting Walt Disney World from August 22 to Sept.1, 2013, it appears as if you won't be able to take advantage of the free dining offer, but one of the other offers could be applied to your reservation if you find it will save you money. I'm not sure how flexible your dates are, but you could also consider moving your reservation into Sept. to take advantage of the free dining.
Melissa, another of my favourite websites for a complete list of all current special offers and discounts at Walt Disney World is Mousesavers.com . They have great information which explains each offer in detail and also gives information on how to book them. You might want to check them out!
I'm sorry that the free dining doesn't work out for your trip, but hopefully you will be able to save some money with another discount - you could then apply that money you saved towards your dining! Please let me know if I can answer any other questions for you, and have a magical day!
