My wife and I are planning a trip to California with our 2 children (12 & 15) in August of 2011. Our plan is to fly into San Diego, rent a car, and then travel for the next 9 to 10 days. We would like to stay a couple of days in the San Diego area and then travel to the Grand Canyon spending a day or two there. Afterwards we will head to Las Vegas, Las Angeles, and then head north to San Francisco. Is this a realistic plan for the 10 days we have scheduled? What are some of the spots that we have to see if this is our only trip to California. I know from experience that some tourist areas are over-hyped and not worth seeing. I would appreciate any help with planning our trip.
