There is NO place more magical and beautiful than Disney with all it's Christmas decor! I love it!

And you will too!
I've been many times in December, but this year will be our first trip actually there AT Christmas. (We're going 18th-26th) If you're going prior to Christmas week, your crowds are very manageable. The week before Christmas, crowds increase dramatically every day approaching Christmas day.

One of the busiest weeks, if not the busiest week, at the World is the week between Christmas and New Years Day. But as long as you do your homework and go with a plan, you'll be fine.
As far as weather...it's Florida...and it can be crazy!

I lived about an hour from Disney for many years and we had some Christmas Days in shorts and t-shirts, and some in heavy coats and gloves. You just don't know. And there's no predicting it even a couple of weeks ahead. More typically, it's chilly in the mornings and evenings (needing a coat and jeans for sure), but nice during the day. Short sleeved shirts usually OK. The main message for weather, is layer. Pack a little of everything, mix and match, and layer for the days.
Really watch the boards as people report on this years activities and you'll be armed and ready with your plan for next year. Have a GREAT time planning!
