Ok, so this is my very first road trip ever! I am excited and very nervous! We plan to spend five days during Thanksgiving vacation and would like to start in San Jose/San Francisco area, drive to San Diego ( we plan to stay with family here for one night), drive to the Grand Canyon (we have no clue where in the GC to visit as this would be our first time), drive to Las Vegas (we would stay with family here), and then back to San Jose/ San Francisco. Is this reasonable to do in 5 days? It would be myself, husband, and our 11 year old son. What attractions can we stop at along the way that my 11 year old would enjoy? Is Hearst Castle along the way on this route? Thank you!
