I agree that you are just going to have to wait until right before you go and check weather.com or what ever web site you choose to check Orlando's weather. The week we went they had a cold snap and I wore jeans and long sleeved shirt the whole time. At night and early mornings was very cold and the kids wore their coats and Micky and Minnie Santa hats. We rode Splash during the Mickey's Very Merry Christmas Party and had a log to ourselves and the picture is weird looking cause we all have on our winter coats!!! But the week before our trip, people's pictures all have them in shorts. I was prepared for the cold since I had checked the forecast. You will enjoy yourself even if it is cool. It is more holiday like that way.
