Inexpensive way to get from OAK to downtown San Fran?
I have some relatives from Italy on their honeymoon. I'm helping them plan their trip. It's their first (and probably only time they'll be able to afford it) in America. They need to get from OAK to downtown San Francisco. I'm not from that area and I've done a search here, but it looks like a cab ride will be expensive.
Someone mentioned taking a shuttle to the BART which will get them into downtown SFO. Is that a difficult endeavor, especially for foreigners who may not understand english very well? Does the BART allow luggage on it? They'll likely have two bags each.
Are there any direct shuttles/vans/buses that aren't prohibitively expensive? My relatives are on a shoestring budget.
