We are going to be there the over New Year's and the first week of January. Since Monday is the legal holiday, my guess is that most folks will leave that day as kids will go back to school on Tuesday. There will some reduction in the crowds on Sunday, Monday will be an improvement over Sunday, but I think it will be Tuesday before it really quiets down. Having been there several times on this same schedule, the early part of January is a great time to visit.
