Some people have listed several restaurants for the same time period for trade on the same day. There is a
free dining code for Disney Visa holders which hasn't been offered in Dec before. We are only 3 weeks out, so most restaurants are booked. Always look at ones in the hotels this close. Always book as early as possible. If you don't find what you want, call daily. Walk up and ask if there are any no-shows.
I booked mine mostly back in October and had no problems except Chef Mickey's.
