I get into SFO at 830am on a Sunday and need to be back at the airport by 5pm. First time in San Fran and want to see a few landmarks and take a photo or two. Travelling solo with no bag, trying to keep it cheap.
I know I can take BART into the city. From that point, would it be recommended to take a hop-on/off bus or should I take transit on my own from tourist area to tourist area?
