Hi, I'm planning a 3 week holiday. Flying into LA, traveling by car to SF and down the West coast to LA and San Diego. Plan to stay 3 nights in big cities (is that enough??), but have no idea were we should stop and stay the remainder of the journey. Any ideas on great sites and things to do would be really appreciated. Have goggled every possibility of others idea's and as yet have had no joy. Want to make sure we get the most out of a once in a life time opportunity.
