Having folding bikes makes everything a little bit easier because it opens up a couple of options for us. First we can take these bikes on Amtrak as luggage, including our bus segment from Eugene to Portland. Secondly, these will fit in the back of a regular sized car, which we will be renting in Missouri to drive from Warrensburg to Clinton ($35 --which is less than taking the Greyhound).
If you get a sleeper car when traveling on Amtrak, make sure you talk with your agent about the Red Cap service that's available. It was great to have somebody meet us at our bus andr transfer all of our bags and bicycles to our sleeper car for us.
We had no idea that this was even possible until the lady at the Eugene Amtrak station told us about it. She was so kind and set everything up ahead of time for us; when we arrived in Portland, Craig was there to greet us with his electric cart.
He took the bags; we got to take a walk and then relax in the Sleeper Car passenger lounge with a beverage.
