We are travelling by car from SFO to Phoenix (Routes: 101 + I-10). We would like to visit LA for one day. In order to avoid going to LA by car we consider staying in Ventura or Santa Barbara and take a train to LA. It takes approx 2 hrs one direction so we can spend some 8 hrs in LA. Does it sound sensible? If yes, should we take a hop on- hop off bus in LA? Again- concerned about traffic.
