Hi. We are traveling to San Diego in July and wanting to rent a house or condo on a beach. Which beaches should we look for or avoid? We probably will rent a car. We will be going to San Diego Zoo and SeaWorld for sure but want a number of days just to hang out at the beach. We like to swim, build sand castles etc.. and do not want it to be crazy busy. Thanks. It will be my husband, myself, and 3 DDs, ages 13, 11 and 8. Jane
