We have an early morning flight into Denver. We are going to drive to Keystone for a 4 night stay. Would it be best to stay in Keystone the entire stay or should we stay in Custer State Park for half the stay? We want to see the Badlands, Mt Rushmore, Jewel Cave, Custer State Park, Crazy Horse and anything else of interest. We are going to stay at either the Roosevelt Inn or K BarS Lodge. Any suggestions on them would also be appreciated. There are 4 adults and 2 children, ages 15 and 8. What would be the best time management itinerary?
