I'm guessing that camps are scrambling for customers right now, because I'm reading about a lot of camp discounts. Here's one I'm highlighting because I know it's a good deal - and a good camp. This is Peninsula Gymnastics in San Mateo. Today through Juice in the City, you can get a week of gymnastics camp for $80 (normally $170). This camp runs from 9-4 daily, and you can sign up by the week or by the day. Dori has been to camp there before (she did several weeks) and had a lot of fun.
The deal is also good for gymnastics lessons, though I'm not sure how they apply the deal. They take kids as young as 20 months for classes.
During gymnastics camp, the kids do gymnastics, tumbling, circus acts in the morning. They put on a little show at the end of the week for the parents. In the afternoons, kids walk to a nearby park and also do arts/crafts. Your kid doesn't need gymnastics experience to go. Camp runs June 14-August 27th, and you can sign up by the day or by the week. It looks like you can buy more than one week on the Juice in the City site.
The deal at Juice in the City is only good through today.
