I am planning a two week trip in August, wife, and two boys age 10 and 12. Week one I am happy with but need advice for week two. Week 1 sat (coming in late sat) sun, monday in vegas, plan do to red rock and the hoover, tues to GC staying there overnight. Wed to mount zion until sat am. Back to vegas to drop someone off at the airport. I would then like to get to yosemite for a few days, through tioga pass and would love to include kings canyon. I don't want a 7+ hour driveand would prefer to have no more than four hours in any one day. Any suggestions as my focus is sightseeing but I wouldn't be upset with san fran or a drive down 1 on the coast. I know, too much to see and not enough time. Thats why I need your help. Awesome site by the way!
