Waterboyz is a great spot for those skaters and surfers in your family.  My kids are still a bit too young for this so I am not speaking from experience, but I have heard nothing but good things about it from friends who have kids that love to skate or surf!  Waterboyz offers lessons and rentals for surfing and skateboarding.  It is a great way to let your son or daughter try the sport before spending the money on all of the equipment.  There are skate and surf camps offered during the summer.
