My family is getting ready to drive from San Clemente, CA to Flagstaff, AZ. I have a 4 yr. old boy and 5.5 yr. old girl. My husband wants to stop in Vegas on the way and spend the night so the kids can see the Pirate show and maybe take a gondola ride. We plan on leaving June 3rd and want to be in AZ on June 5th. What will be our best route? Any ideas for more stops along the way? How about things to do in Flagstaff besides driving to see the Grand Canyon?
