We're a family of 2 adults and 2 children, aged 12 and 14, from England. We'd like to visit west coast San Francisco, Canyon, Yosemite, Vegas and LA in July next year. Would like some advice about best way to get around 9RV?), best route and towns to stay over in. We'd really like to stay at a 'ranch' and with the children, limit the daily hours travelling. We have approx 3 weeks. Any advice? Thanks
