We are so excited to be visiting SF! We are arriving at SFO and wanted to know if there is any bus/transit services that would take us from the airport to Fisherman's Wharf. We will be traveling with carry-on luggage and I am not too sure that these would fit under the BART seats. We have been told that we will probably have to use the shuttle buses and to plan on spending $90 for that form of transportation. Thank you for your replies!
