If you are going on a trip or vacation, you can reserve a room at the Oakland Days Inn under "Park and Fly". Under this plan you can park for no additional charge and they offer a free shuttle both to the Oakland airport and back to the motel upon your return. If I remember correctly, the rate for one night comes with Up to 14 days of "free parking". If you will be gone longer, there is a relatively small additional fee. We have used this many times. In my mind, it is one more reason why flying out of Oakland is a great choice.
