The first two weeks of December are the least crowed. Try to go on a weekday as the weekends are really busy. My wife and I went last year the second week of Dec and we had a ball. Here are some links to the Christmas events. Have fun.
In the beginning of Dec. it is crowded because that s when they have all the cheerleaders from all over the US competing. They hold the Competition there. Its from the 9th this year and lasts about a week. If you call there they will tell you when. All the hotels are full and its very crowded.
The first 2 weeks in Dec.are the best time to go. The weather is great and crowds are low.
