for those of you that are unable or uninterested in the alcatraz tour, yet would like to get a little tour of san francisco please take a look at the alternative suggestions we have provided.
1. renting bikes - bikes can be rented from many places...most popular spots would be market street, near 1st street, for closest access to the hotel, or many more options in fishermans wharf area.
2. go car tours - this is a quick and FUN way to get a historical (and very interesting) tour of the city
