2010 Free dining ????

[disneyfreak7]

Does anyone remember what was the minimum ticket purchase to get free dining? We had annual passes during our trip in 2010 but it was worth it to buy minimum ticket to get free dining for our family of 7! I am trying to figure out how many days I have on our blue "key to the world" tickets that we did not use. I called Disney and they are not able to check how many days we have on our tickets
