I am planning a road trip for my friends from overseas and would appreciate ideas and suggestions. We are four people and plan to travel by road from San Diego, to Los Angeles and tour Holly Wood and Disney land. Then travel to San Francisco by the coast and while there see the Golden Bridge and major attractions in the City. Then fly to Las Vegas and tour Grand Cayon and Hoover Dam and ofcourse see some shows. We have one week for this trip. Any suggestions on good places we should visit ?
