Arriving at the new San Francisco International Airport alone I had to find a way to get into the city. I literally walked outside and there were numerous people working for shuttle bus companies trying to get you on to their bus. From what I could tell, there is really no difference between the companies, if there is a shuttle waiting just hop in. If you are in a hurry, it may be a good idea to ask the driver how long the trip will take to your destination as they decide the order in which everyone is dropped off. By the way, the new San Francisco airport is ultra-modern, sleek and very minimalist. Be sure to take a look around!
shuttle - $13/per person each way.
cab - $30/per cab up to 5 person each way.
limo - $30 - $50.
We prefer that unless you are from a busy, metropolitan city, where the steering wheels are on the left side, don't drive here. People are not polite, traffic is dense, and there are too many cars for our small city, parking is crazy and expensive, take a cab, bus, or walk, you'll see sights better anyways.
Take the 'super shuttle' from SFO to the city, you'll save money on the cab fare.
Avoid MUNI (our public transportation system) they suck bigtime. However, BART and CALTRAIN are great. Try walking, it's a small city and you might find something interesting along the way.
We flew. The airport isn't that far away. If you can arrange it, try to get transfers from your hotel ... it's cheaper.
Like I said before, use the buses. Or try walking those hills; you'll be in the best shape you have ever been in a long time!
No need to worry about this. Most of the hotels propose a shuttle service for 10-15$: much less expensive than a taxi and much more confortable than a bus...
