Howdy,
[you don't mention if you're
DVC or cash person, but I'll assume you are DVC since you posted to this board!]
Christmas week can be nuts...lots of people trying to fit a complete vacation in a relatively short period of time. If you go expecting a crowd, get to the parks early, then not worry about doing all of the attractions as the crowd builds, you might find the volume of people and the waits tolerable.
Wifey-poo and I don't like Christmas week because of the crowds, but when we went for the tail end of the week last December, we got to the parks early, did the 3 rides we wanted, then just relaxed, people watched, and headed out early. We knew we'd be back, so we did feel as if we'd missed something. In fact, we actually got to ride the train around the magic kingdom for the first time after a number of trips....
As mentioned, you may not be able to get a room though DVC at this late hour. Christmas week is the busiest of the year, and from what I've read, seems to fill right at the 11 and 7 month marks. However, we were able to get NYE weekend last year in a studio at BWV on 2 months notice, no waitlist....so don't not try!
As to earlier in December, the DVC guides seem to all mention how nice it is to visit during early December because of the 'lower crowds' and WDW is doing all of the holiday stuff. What they fail to mention is that it is one of DVC's busiest times because:
1) Lower point costs per room.
2) Holiday Decorations and activities are attractive additions to (1)
3) DVC'ers are (generally) smart enough to realize how much better it is going in early December than most other times of the year.
For these weeks, it seems most of the time you really do need to have an 11 month window at the resort you want, unless it's OKW which has more rooms to allocate.
