Hi Stacey! You are going to be visiting Walt Disney World at a wonderful time! The
Epcot International Flower & Garden Festival will be on at that time, and it is really a fantastic event. Just click the link I've provided if you'd like to find out more information.
Spring weather can be kind of crazy! One day it can be sunny and warm, and the next, cool and windy. Florida is no exception, therefore it is very difficult to say what the weather will be like while you visit. I know that the water in both Typhoon Lagoon and Blizzard Beach is heated, so that does help if the temperatures are a bit cooler. Both parks should be open while you are there, but they do sometimes close them if the temperatures drop too low. Let's keep our fingers crossed and hope for loads of pixie dust that you experience nothing but warm, sunny days, and that you will have a great day to enjoy one of the water parks at Walt Disney World.
Please let me know if I can help you with any other questions, and thank you for visiting the Disney Parks Moms Panel. Have a magical day!
Kristen
