We were there that week in 2011 and we had great weather. It only rained one morning for a few hours. Other than that it was sunny and in the low 80s. At night it can get a little chilly so I would recommend packing sweatshirts/light jackets. It doesn't hurt to throw a rain poncho in your suitcase either, just in case there is a pop up shower. Enjoy! You've picked a great week to go to WDW!
