Hi there Bonnie. Enjoying the
Disney dining plan is even more delicious when it's offered for free!
One of the best predictors of possible future deals is to look at historical data on past releases. I'd recommend visiting the
unofficial website www.mousesavers.com and in the search box at the top left hand corner of the page, type in "chart of past discounts" to peruse this information. In 2012, Free Dining was not available in May however, it does appear there was a resort room discount. Sometimes, the savings on the accommodation portion of your trip can cover the cost of purchasing a dining plan out-of-pocket so, you'll need to analyze your options nearer to your vacation dates.
Be sure to keep a close eye on the
Special Offers section of the Walt Disney World website in early 2013 as you never know what magical deals you might discover!
