KidZoo Camps helps parents find summer camps for their kids based on their budget (e.g. $400 per week), hours (full day, extended day, half day-morning or afternoon), as well as distance from you, based on zip code.
After parents like a camp, they can choose the weeks they want to send their kids, and send an indication of interest to the camp directly. They can do this for all the camps that sound interesting to them.
