Greetings Charlene,
Thanks for stopping by the Disney Parks Moms Panel with your question! My family loves the Disney Water Parks and have previously bought Water Park Annual Passes in order to make frequent trips each year.
Based on my own personal experience with my four children, I recommend
Disney's Blizzard Beach Water Park for your 4 and 6-year-old. With its unique theming, Chairlift and thrilling family raft ride, Disney's Blizzard Beach Water Park is unlike any water park I've previously visited. Although my family does love the Surf Pool at Disney's Typhoon Lagoon Water Park, we found it to be too intense when our children were younger. We found Melt-Away Bay at Blizzard Beach to be the perfect level of intensity and fun for younger Guests. What truly sets Blizzard Beach apart for our family is the
Ski Patrol Training Camp. My four children could honestly spend hours in this one area of the park in order to continuously attempt crossing the Thin Ice Training Course and experience the thrilling zip line, also known as Fahrenheit Drops.
I hope this information has been helpful in making the best decision for your family. If you have any additional questions regarding the Disney Water Parks, please don't hesitate to reach out again. Best wishes for a magical trip, Charlene!
Happy Planning,
Jodie
