I went to wdw from Feb 7-14 2015. We had a very wide variety of weather. We were only able to swim 1.5 days because otherwise it was too cold. It was very cold in the mornings imo. I am from NJ fyi. It Poured the entire day we were in Epcot and luckily we had packed our rain shoes and waterproof winter coats and stroller rain cover. The best thing I packed for my daughter was a down vest for layering everyday. But otherwise we mostly wore lots of layers. I would be on the safe side as we definitely had a cooler than average week. It felt great for walking around the park thouhh. Very comfortable.
