We are doing a combined Disneyland/San Diego trip the week before Labor Day and my daughter wants to hit the beach one day. I've narrowed it down to hitting either Coronado Beach when we are down in San Diego, or Santa Monica when we are in Anaheim (Huntington or Newport just don't hit my fancy for some reason). Which one is better for just a relaxing beach day, with maybe a bit of wandering/relaxed tourist-type shopping thrown in for good measure? (I'd like to park the car and leave it.) Which generally has the clearer water? Which generally has gentler waves?
