I thought that
free dining was not being done through December anymore

I could be wrong on that (most likely I am though).
We're also going to be down there the same days. Only we are trying to decide whether or not to go December 2 through the 10th or the 11th or go from December 2 - 10th. We may choose the latter b/c the return airfare is more expensive on Sundays if we were to go on our original dates.
I'm hoping there will be pin codes available. I don't know if Disney will still have them with Pop Warner that week or if that will be considered a black out week.
