My info, don't go! We were at WDW a few weeks ago, December 8-18. The most crowded, longest waits, etc. at MK we experienced were as follows:
1) Saturday Dec. 17 - Estimates of 50,000 by cast members.
2) MVMCP Dec. 13th
3) Sunday Dec. 18
And we were in parks from opening to close most of our stay.
1) and 3) were possibly mainly due to crowds picking up before the holiday rush and locals looking for holiday spirit on the last Saturday before Christmas Eve. The Christmas party was not worth the money in our opinion (ours only, others have different ideas). $40 bucks each for cocoa, fair tasting cookies, a parade and fireworks. We did as suggested, seeing later parade, trying to go against the flow, arriving early and leaving at closing. Lines for rides were consistently some of the longest during our stay, with barely room to walk.
My suggestion would be to save the money spent on tickets for a family and use it towards and extra room night and extra day of regular park admission.
Yes, the fireworks were great (we liked the holiday ending to Illuminations better) and the parade was cute, just not $40 bucks each cute. If you're just looking for the special activities and cheap looking photo they give you, you might enjoy being elbow to elbow with half the planet. If not, and you are planning to enjoy many of the regular attractions, you may be dissapointed. We have been to
MNSSHP party and it was nothing like this. Remembering the monorail speil talking about the party being "an exclusive night in the park" still makes me laugh.
If you go in '06 I wish you much better luck than we had.
