No, I don't think you are nuts. I think Christmas is one of the most special times that you can spend in WDW, & by "Christmas" I mean, being there on Christmas Day. (I never quite get all the people who say/post that they are going to WDW for Christmas & then post their trip dates and they are going in at some other time in December, or even November. That's not Christmas people

).
My family spent Christmas 2007 (Dec. 20-26) at AKV and it was our most special Christmas and WDW trip ever. We did the final night of
MVMCP, the Poly Luau, Wilderness Lodge sleigh ride, photo ops with Mickey & Minnie in their holiday attire, etc.
It was so nice not to worry about cooking (I NEVER, ever cook in our villa..we eat every meal out), laundry (never use the washing machine either

), wrapping gifts, last minute shopping, etc. I got to enjoy the FUN, FESTIVE part of Christmas, every day, every minute, without any of the headaches.
We enjoyed low crowds at the parks until lunchtime on Xmas Eve (we were at AK that day. That's when I noticed crowds had increased & we made that our last visit to a park. Luckily, I had made our ADRs for Xmas Eve dinner & Xmas day at resorts....1900 PF, 'Ohana, & Chef Mickey's.
I really hope we can travel there again at that time of year. What a special trip that was.
