Who the heck takes the cable car for transportation? Thats a tourist trap that you should do once only. Take a cab, or even better, ask the front desk which muni will take you to the wharf. Its so easy to get around SF, but it helps when you live there and know it well. Just ask anyone...they are friendly folks!

And avoid the fanny packs! (and for that matter, anyone dressed like they are on vacation to "warm" California!)
