Hi. I'm travelling to Cali for a wedding in Sonoma. I want to spend 3-4 days in San Fran before heading north to Sonoma. Should I rent a car for the whole week and have a car while in Sonoma AND San Fran? If so, can you recommend a hip/nice moderately priced hotel in an area where parking is not a problem? Or is parking too much of a hastle in SF? should i just rent the car when heading north to sonoma?
