Not any more dodo duck, it's all one ways, even if you ride to Tiberon through Sausalito, you get a freebee between Sausalito and Tiberon but you wind up having to buy a ticket between Tiberon and SFO if you get off the ferry, best you can sneak by with is one round trip just for the ride. When we first started going to SFO on a regular basis you bought a ticket that was round trip, you could go to Sausalito get off and hang around a bit get on a later ferry go to Tiberon and get off and spend some time then get on another ferry and head back to SFO.
