Actually we went to the MK on New Years Day this year and the morning was great! We were there at opening (I think 8:00 am) and the park was very slow for the first few hours. We were able to do a lot. By noon it was pretty busy but then we started using the fastpasses we had picked up in the morning and we went on less popular rides. By about 5:00 we had had enough of the crowds and headed to Epcot. We thought that MK would only get busier because it was the EMH night. Epcot was fine, we really didn't do too much because the kids had run out of steam. The next day while on a bus to a park, we spoke with a man who said that the MK was great in the evening, very little waits. Too bad we didn't just stay put. If I could do it all over I would go to the MK early in the morning, take an afternoon break, go back for an early dinner (5:00) and stay for the evening.
