We're planning going to Yellowstone in the summer. Any ideas of an itinerary would be most helpful. Mt Rushmore is an obvious stop. Badlands? Any other places that would be nice to visit that's near the route (I-90)? It will be me, my wife, and 3 kids, ages 7-13. I have at least 11 days to work with, Friday to the next Monday. That gives us 6 days of driving, 1 day for Rushmore, and 4 days at Yellowstone. But I could push it to 12 or 13 days if I needed to to get the most of the trip.

For example, looks like we could divide it into 3 days. About 8 hours into Wisconsin, another 8 hours to Rushmore, then 8 more to Yellowstone. How much time should we expect to stay at Rushmore? Can we visit that and do 8 hours of driving in one day?
