It's summer in Florida, so that means it is water park time. The two most popular parks in the United States are Typhoon Lagoon and Blizzard Beach, both located at Walt Disney World. Each one gets about 2 million guests per year. Today, we had a blast at Blizzard Beach and our son enjoyed some of the big slides for the first time. However, he has yet to conquer Summit Plummet, the tallest and fastest water slide in the country.
