Harbor first
The classic landfall
Day 1. Embarcadero: Midway or Maritime Museum, walk to Seaport, supper in Little Italy or the Gaslamp. Day 2. Full day in Balboa Park—zoo or museums, not both unless you are made of oak. Day 3. Morning ferry to Coronado; afternoon La Jolla Cove if you still have wind, or Sunset Cliffs if you only have an hour before the airport.
