I would think it will be very crowded during the weekend. That weekend they are taping the Christmas parade at MK. Availability at the resorts is almost non-existant. I tried for weeks to add another day to my AKL reservation (Monday the 5th) and can't get another day of the same accommodation/discount. There are some conventions going on and the big pop warner groups are coming in. (I guest the lots of folks for the taping, along with Regis and Kelly.) We went the second weekend in December last year (10-13) and had to wait 1 hour to get into MGM because the lines at the turnstiles were so long (had actually heard that MGM reached capacity that Saturday night). So I moved my trip to the first weekend this December and hoping it won't be as bad. We could barely move in EPCOT last year during the weekend. (We were at the tail-end of the Pop warner group last year and they were everywhere, but mostly at the value resorts and a few moderates.)
