I paid $400 for a roomette on a 15-hour Amtrak train. The 23-square-foot space was more comfortable than I expected.

A 23-square-foot roomette on Amtrak's California Zephyr train provided a cozy and efficient space for a relaxing 15-hour journey through the American Southwest, offering comfort and relaxation for locomotive enthusiasts despite being more expensive and slower than flying or driving.
