Hi.
Disney Mom Jackie's
answer that you are referring to does include information about a 2011 free dining opportunity that was available for your vacation dates.
However, this Free Dining offer was released on August 16, 2010 and had to be booked by December 20, 2010. It covers the dates of August 19 - September 29, 2011.
Through the years, I have learned that the best way to take advantage of discounts including Free Dining is to consistently check for
Special Offers. You can do so by following the Special Offers link on the WDW website at www.disneyworld.com, checking out a site such as www.mousesavers.com and/or securing the services of an Authorized Disney Vacation Planner/Travel Agent.
Then the next most important thing is to make sure the offer covers your vacation dates. If it does, book it right away. Most offers have limited availability and also have restricted booking dates. For the offer above, no reservations were accepted after December 20, 2010.
While this doesn't help you now, please continue to watch for additional offers. In 2010, free dining offers were released in May and July that covered the same dates as yours for 2010. Therefore, you may find an offer that becomes available 1-3 months before your travel dates.
If you see an offer, call and ask if it can be applied to your reservation! I wish you well in finding a magical discount!
