Rumor has it that WDW will be offering free dining to the general public starting Thursday July 12!
This is always one of the best discounts available at Disney. The amount of rooms at each hotel for this offer is limited. Remember, if you already have a trip booked during this time frame, you can apply the promotion by calling Disney. Your arrival date must be within the promotion dates. You will also be charged the new ticket prices, if you booked before June 3.

Update 7/12/12: The dates are accurate. Remember you have to arrive for your trip within that window to receive free dining. Also, to get free dining you must book a 6 night/7 day vacation.
