From the San Jose Mercury News article:
With summer underway, parents — particularly those who work full time — face the challenge of coordinating weeks of activities for their children.
Whether your kid stays home with a baby sitter, takes swim lessons through the local parks department or signs up for a dizzying array of camps, the logistics involved in patching together activities can be overwhelming.
Now a host of startups, including ActivityHero, ActivityTree, Camperoo and Famtivity, have sprung up to streamline the process for parents. Part clearinghouse, part community bulletin board, each makes it possible to find and book summer camps and recreational classes for kids online. The Web-based services are supported by ads and are free to parents.
