if (and it is still an if) we were to go to San Francisco next month

and, hypothetically, went for ten days, how long should we stay in the city, and how long should we devote to tootling round California in a convertible?

and what are the "must-sees"? Alcatraz, Golden Gate, Monterey Bay Aquarium, Fisherman's Wharf, cable cars ...

anyone know any inexpensive hotels in the city?
