They wouldn't give me the free dining (didn't think they would), but I still have hope, and here's why:
I reserved this trip with a PIN that I got in my email. A couple of weeks later, WDW published discounts for everyone. I called to see what the difference was between them, and they were exactly the same. So maybe, in a couple of weeks, there will be a general free dining promotion?
The CM I spoke with said to keep looking for discounts on the Internet. That may just have been her trying to be nice, but I'm hoping it was secret code for "Free dining is coming soon!"
