Another thing to consider are all the December special holday happenings, including
MVMCP!
The #days "Donald is #1" suggested is good - but you still won't see everything - nor should you try.
I'd recommend getting a guide book or two - I like the "Unoffical Guide" - and go trawling for info on the disboards and ears-to-ears web sites:

Try to get the other adult and DS involved in the planning and prioritize what each of you want to see and where you want to eat, etc.
Don't wait for the airline fares to make your WDW ressie - it looks like rooms are booking up fast (especially at the
AAA rate ...) for December - so if you know where you want to stay (assuming it's on-site) I would book it as soon as you can. It will only cost you a $200 deposit - and you could change the ressie later if needed.
Finally - we'll be heading to WDW in early December, too - and to toot me own horn, have started a pre-trip planning report:

Granted - it's geared to my will-be 5-year old DD ... but it should give you some ideas ...
If you have any other questions, I'll be lurking ...
