WARNING, you should pack for summer and winter. We were at the World December 2006 and were glad we did. It was cold the whole week, except for one day and we still had to wear long sleeves. We are very hot natured people and I usually wera flip flops even in the winter, but for me it was even too cold to do that at WDW. Even though we were dressed warmly, we still had to buy some blankets in EPCOT to keep warm. We left warmer weather at home in East Central Alabama. The highs might have reached 40 and the lows were close to 20, but then I saw pictured of people later in the month and they were wearing tanks tops and shorts.
