We are planning on grabbing a taxi from SFO to The White Swan and back. We will have too much luggage to bother with the BART. While reading a guidebook today, it said that it is almost impossible to get a taxi in SF and a taxi should be reserved to go back to the airport. Seems odd. Wouldn't the hotel be able to get us a taxi. Also, we are only renting a car for day trips to Napa and Santa Cruz. So, we were also going to use taxis at times for dinner. Is this going to be a problem?
