Mid to late April is our favorite time to go. It's great to get away from the still cold northern weather. Daytime is great for water parks & evenings are usually warm. Normally there is very little rain--although one year we did have rain probably 3 days of our 9 day trip. We love Epcot & it's extra nice that the Flower & Garden Festival & the wonderful Flower Power concerts are going on then. We'll be back the 16th to 26th, ourselves. Have a great trip!!
