Early December is THE busiest time of the year for DVC, and many DVC owners use the dining plan. The December trip mentioned in my post above took place exactly during that period.
Dining at Disney today is very different from dining there even 3-4 years ago...and it's not all good.
I'd be looking for DDP alternatives, like the DD restaurants and some of the restaurants at the resorts. There are some very good choices there, but I think Epcot and MK are going to be very difficult.
