Hi,we are a family of 2 adults and 2 children under 10 years. Around late August/early September we are flying from London to Sydney (a long term move), and we are considering stopping somewhere on the west coast of N America for a short driving holiday. At this stage any suggestions or advice would be welcome ie a week in the areas around SF, or fly into one city then drive to and fly out of another (Vancouver, Seattle, SF?). Car hire and accommodation options? Thanks in advance.
