Trying to plan a trip to US West area for me and my two college-age kids in May of 2013. Ideally, it would be a 7-9 day trip including Mount Rushmore, Yellowstone, maybe a dude ranch or boat trip and Gold Rush towns. I am totally open to ideas!! I have looked at several tours because I don't want to drive myself, but they are expensive and the hotels are not great. Am interested in traveling by train, and adding a leg or two on a bus and/or boat rather than having to rent a car and drive myself, I can depart from Denver or Fort Collins, CO area OR I can fly somewhere direct if there is a good option for this type of trip. I would greatly appreciate any advice. Is this even possible?
