The
free dining package is available for package stays beginning August 13 thru Sept. 30, 2006. The dining package normally costs $37.99 (adult) and $10.99 (child) per night. The package includes one table service meal, one counterservice meal and one snack per night per person. This can add up to a significant savings on your food budget.
You can get the free dining on your package by booking thru a
travel agent or calling Disney yourself. There are codes associated with the packages but you should be able to book without the code as long as you ask for the free dining. You can also book online by going to WDW's website, clicking on Tickets & Reservations and then clicking on the the "Special Offers" link.
