We are planning a trip to San Francisco in July. We fly in late Monday, July 3rd and fly out late Saturday, July 8th. That gives us 5 full days (counting Saturday, our fly out day, but we don't have to leave for the airport until 8pm). We are going to use at least one day, maybe two days for Sonoma/Napa. So that leaves us 3 days in San Francisco. I figured we would do the hop on/hop off double decker tour, Alcatraz, Fisherman's Wharf, Chinatown and the painted ladies on Alomo Square. What else are must do's?
