Hi KenCT,hope you can make it.
Actually while not a total pain Bart from Oakland is a bit of a PITA with the airlink shuttle exthoring an outrageous fare from those customers wishing to take bart into the city-it is a long walk through a less than lovely neighborhood so they know they have you by the testes on this.

From SFO there is a free airlink train connecting all terminals and it is a joy to be able to take Bart right into The City now.
