We will be visiting San Fran next week and have limited free time. My DD would like to visit Alcatraz and the Disney Family Museum but our only free day is Thursday. Is it possible to do both on the same day? If we did Alcatraz first thing in the morning how long should we allow for the ferry ride and tour? We would then take a cab out to the Presidio in the late morning/early afternoon to visit the museum. If this won't work, what other attractions would you suggest to visit at the Presidio?
