Everyone should experience Disney at Christmas at least once. It is so beautiful. If you go knowing there will be crowds and plan ahead, you will be fine. We have been twice during Christmas(once the day after, and last year during). On Christmas Eve we did the Candlelight Processional dinner package. Ate at LeCellier and then did CP. Christmas day we went to the Magic Kingdom, knowing it would be crowded. We just went with the flow and did some major rides in the morning, watched the Christmas parade and then went to the Liberty Tree Tavern for dinner. It was a magical day. Be sure to get PS's in advance. The rest of the week was busy, but manageable. We have been enough that we know what we like to do and plan around those activities, including golf and pool time, when it is warm enough. We try to enjoy our resort as well as the parks. It makes the whole vacation more relaxed.
