I'm staying in San Francisco for a couple of days and will be driving up to Tahoe. I found the best deal for a car rental at the Oakland airport. I plan to take the BART there to pick it up. This would be on a Friday. I thought I'd go back into SF and pick up the wife and kid, saving her the trouble of dragging luggage on the BART. But I can't pick up the car till 4 PM so I fear the traffic will be a nightmare over the Bay Bridge. We're staying at the Parc55. I'm thinking lug the luggage...Any comments?
