We went this past January (9th-15th) and it was great. We too are from up north so getting away from the snow was great. The weather was pretty nice, in the morning and later at night it was chilly, but we were fine with sweatshirts. My DH wore shorts every day, and I wore jean capris and flip flops. One day I wore a long sleeved shirt and was sweating by mid afternoon. The only time I was really cold was when we were waiting for Fantasmic to start. There was technical difficulties so we had to sit and wait about a half hour to 45 minutes after the show was going to start and sitting on the metel bleachers was starting to make our bottoms numb, but we had a blanket with us so we put it over our legs and grabbed a hot chocolate from the concession stand and it was fine. The only thing that we did not like about January was that one of our favorite rides (Splash Mountain) was closed for its annual refurb, and the large amount of Brazilian tour groups. Other than that the crowds were pretty low, we arrived the last day of the marathon weekend so after the first day most rides were walk on. Overall we enjoyed going in January.
