Where's the best place to stay if you want to see lots of things around San Diego, but would also like a quiet beach to relax on some days? Folks seem to say that La Jolla Shores is the nicest beach to stay near. If our family with 3 daughters (16, 13, 9) finds a vacation rental near La Jolla so we can go to that beach easily, will all the sightseeing be too out of the way? Or do people not really go to the beach much (i.e., it's not Florida, right?) We're planning a summer trip.
