we went in 2010, the weather was nice for 4 days then turned really cold,=50's during the day and 30's at night, we had pre planned and purchased our tickets well in advance,for the mvmcp, so we had no choice but to go, we had to buy gloves, hats, and jackets, was 4 layers deep, and still got very cold, so left before 9:00pm, also they film the ABC Christmas Day Parade usually the 1st Friday of December, so you will want to plan around crowds @ MK, also gets dark around 6:00, so make sure you pack clothes for all kinds of weather during this time of year, October was a much better visit, but the Christmas decorations were pretty, just be prepared
