If you've left your brain at the office and want someone else to make all the tough decisions during your vacation, you'll love this section. It's where I tell you what I think you should see and do during your vacation in San Francisco. It's broken down into One Day, Two Day, and Three Day sections, depending on how long you're in town. If you've already made your way through "The Best in One Day," the Two Day tour starts where the One Day schedule left off, and so on. But if you really want to enjoy even a fraction of what San Francisco has to offer, you should plan on staying at least three days, preferably a week. And because renting a car in the city is an expensive hassle (and driving in the city is insane), we're going to do all our transportation via foot, bus, and bike. Right, then: Let's get started.
