We were there at the beginning of the year, Dec 31-Jan 6. I went with the understanding that it would be very busy. My biggest surprise was the day we went to Animal Kingdom - it was packed!. Magic Kingdom was great on Jan 1. We did everything we wanted with FP and a couple of early mornings. We followed the crowd calendars on Touring Plans. The worst part was the QS restaurant at POR - by the end of the day I always found it really messy and they were out of a lot of things - drinks, ice, cream, etc.
