underwear and tooth brush are definite requirements. (Just kidding). I would just pack for disney like any other warm climate vacation. Unless you are going in Mid Dec. to early Jan. Florida had some cold winters this past two years. Once or twice it was 58 to 60 on Dec. 20th or so when I was there. So I would say pack so that you can layer clothes in case there is an 80 degree day or two. I would also recommend rain ponchos. If you don't have them don't worry you can buy them there for cheap, I just always forget mine.
