Hello, I am planning a road trip (Round trip) from Quincy, MA to Los Angeles, CA in April, 2019. I'll be driving my car and will be travelling along with my wife and son. I'd like to know which would be the best route to take? I would like to stop by in Chicago,IL and Grand Canyon, AZ. Could you please also provide a conservative estimate as to how many days would i need on the road for one way and a round trip?
