The CP is the most beautiful thing at WDW during the holidays IMO. It is in the American Gardens theater at EPCOT (outside but covered.) They have a full orchestra and choir. The guest reads the Christmas story from the Bible and the performers do Christmas music. I think the readers are announced in August or so, but sometimes things get changed. You do not HAVE to schedule a dinner package, but it reserves you a seat for the show. Prices vary based on which restaurant you choose. If it is a popular narrator at a popular time I think it is best to schedule a package. There are three shows a night, the earliest one is usually less crowded because it is not dark yet. Many people prefer the later, darker shows. I think it is not to be missed, unless you are not Christian. My kids have done it twice, once when they were pretty young, and we love it. My kids have no trouble sitting through it, but we do go to church (it is, however, much more interesting than most church services!) Enjoy!
