You're new here so you may want to spend some time going back through the last few pages of posts...there's so much about DVC that they don't tell you about.
The first two weeks of December are always a very busy time for the DVC. There are a few things conspiring to make it so:
1) LOW point cost.
I think Disney wants it this way...this is a slow park time and encouraging thousands of rabid DVCers is a good way to fill up some of the empty spaces in the park.
2) LOW park attendence.
Bracketed by two major holidays (and school breaks), most parents are loath to take kids out of school. Even thousands of rabid DVCers can't fill the parks...especially since most of us now relax on
Disney vacations...no more commando park missions means sometimes not running the parks all day.

3) Holiday Decorations
The World is done up for Christmas.
4) Annual Meetings.
Some day we may even go to one...if we can get out of the
parks or off of the balcony.
5) LOW point cost.
You'll probably find OKW will usually have _something_ available as its a pretty big resort and doesn't have all of the immediate 'entertainment' the other resorts have. Common wisdom seems to be always make the ressie you can make and waitlist the room you really really want.
If you have any other questions, you can try the search engine on the board.
Hope this helps,
Joe
