Walt Disney World in Florida has two great Water Parks, I have been to both! I had fun from the monent I walked through the gates until the final drop of water dried on my legs.
The two Water Parks; Blizzard Beach and Typhoon Lagoon, are designed beautifully and equipped to give thrills for all ages.
One thing I found quite nice is the organization of Disney staff and the multiple levels of safety provided for their patrons. I noticed the parks filled with lifeguards, and other professional staff: to watch over children who were lost, ensure ride safety and provide water safety. I truly felt safe and I felt my children were safe.
I will post pictures of Blizzard Beach and Typhoon Lagoon soon, stay tuned!
