Depending where you are starting from..... The I-15 from Salt Lake City to the 20, to West Yellowstone, is pretty straight. And if remember right not much climbing. From West Yellowstone, getting to Yellowstone and the Grand Tetons is not much trouble either. Staying in Jackson can be kinda pricey depending on the time of year. I would opt to drive the park in a car. Easier to get parking etc. However, the 14 can be twisty (from Yellowstone lake area). But, again I don't remember the climbing part.... Which usually means it wasn't bad. And Cody is, for the most part, windy.... And I hate the wind..... But from Cody it's pretty much a straight shop to Mt. Rushmore. Sounds like a nice trip, have a great time and be safe!
