Next time you have visitors and know you’re going to hit some of the gems of SF, buy one of these: City Pass. Unlimited rides on the cable cars, (5$ a pop per person), entrances to key museums, and a ride to Alcatraz. A savings of about 55$. I wish I had known about this a few relative/friends visits ago. Sister- who is local and works at a local museum- forwarded this to me because she thought the SF Metblogs community might benefit!
Spans 9 days too. Youth rates- 39$. Kind of flexible: you have an option to swap out the Asian Art for the Natural Science, and you can swap out the Alcatraz for a Bay Cruise. Neat!
This reminds me of the cool MUNI tokens that I found out about after living here for 5 years.
