Hubby and I going to be in San Francisco for 4 full days and 5 nights. Taking a Dylan Tour first day and want to do Alcatraz and Sausalito as definites and have researched. Also will be using public transportation and staying at the waterfront. Is it worth it to buy the CityPass with the Alcatraz exchange? Or better to buy a Muni Pass and an Alcatraz ticket separate?
