Hey there, Dianna!
Thanks for stopping by the Disney Parks Moms Panel with your question! I'm so excited to hEAR you are visiting Walt Disney World Resort in May!
My family loves the Disney Water Parks and have visited both Disney's Blizzard Beach Water Park and Disney's Typhoon Lagoon Water Park "minnie" times. As a mom of four including 13-year-old twin boys, I recommend
Disney's Blizzard Beach Water Park for its unique theming and thrilling waterslides. Although my children could spend hours in the Typhoon Lagoon Surf Pool at Disney's Typhoon Lagoon Water Park, they find the waterslides to be more exciting at Disney's Blizzard Beach Water Park. Your 8-year-old will also love the
Ski Patrol Training Camp, a fun area for kids and preteens. That being said, I do think your children will enjoy both water parks if you find you have adequate time to experience both.
I hope this has been helpful in making the best decision for your family. Please visit us again if you have any new questions. Best wishes for a "splashtastic" trip, Dianna!
