I'm going to SF next week. What's the best way to get to the centre? I have a Uber account for London.
However, the ideal transportation if you're visiting is to simply walk around. It's amazing how easy it is to walk everywhere in SF.
For Alcatraz, just grab a lyft/uber to the pier and take the ferry. By the way, if you have time the longer, late evening tours are quite interesting.
And also sold out months in advance.
AirBART is the shuttle bus service between OAK and BART. http://en.wikipedia.org/wiki/AirBART
