We will be arriving in Florida December 27th and leaving January 3. We need to pick a day to go to Universal. We are also planning on going to the Magic Kingdom and Epcot while we are in Florida. I know it is probably the WORST time to go to the parks but it was the only way we could go and the kids wouldn't miss any school. Can anyone give me an idea of how busy it will be and what the best day to go might be? Thanks.
