I will start my five-day trip in San Francisco next week. I booked a hotel in the Oakland Airport area, because the hotel there is cheap, compared to the price in the SF area. Just now I realized Oakland is not a safe city. So I am thinking to cancel the reservation, and book one in SF area. I purchased the hotel through Hotwire, not sure if I can get the refund. But before I do that, I just want to get some suggestions from the folks here. Should I cancel the hotel in Oakland? Is it convenient to drive to SF and nearby places from Oakland?
