After our amazing road-trip last year from Washington DC to Vegas (thanks for all your help by the way), me and my Dad are going back for a further 10 days probably around May this year. Our plan is to start in Denver and then make our way to Yellowstone National Park. What is the best way to get from Denver to Yellowstone and then back to Denver? We want to see places on the way and wondered if there is a good train service or bus/coach service that we could look at.
Or, is hiring a car the best option?
After that we are going to take an internal flight to Nashville for a few nights as we both fell in love with that place last year :-), was awesome!
Any ideas would be a great help.
