I think it all comes down to your ability to drive long hours. I know I can't drive as long as I did when in my 20s. I get really get tired after 350 miles and six hours seems to be my max before I start to get sloppy.
2X. When I was younger I drove semi and would do 700 miles a day but it took around 15 hrs. Now days putting on 350 miles is a real chore and after 6 hours of driving I find myself not as alert and my back hurts. Safety should be you main concern with the family and there is a lot to see between your home and Yellowstone that would make the trip even better and safer if you made a few stops.
