I am looking a dates for a much wanted Disney World trip. I wanted to take advantage of the free dining offer so I was thinking about taking 1/22 - 1/30. Do you think it will be to cold for the water parks? What would we need to wear during the day in the parks? We went the beginning September one year and it was super hot so I would not mind going when it is not so hot - just not cold. What do you think??
