Amtrak’s California Zephyr and Coast Starlight Superliner Roomette offer some of the most breathtaking scenery America has to offer in the comfort of your own private cabin. In this trip report, I travel cross-country from Chicago to Seattle via Sacramento on the California Zephyr (50 hours) followed by the Coast Starlight (20 hours), both in the Superliner Roomette First class cabin. Cabin amenities include two chairs, two convertible beds, full meals, and showers. Where else can you have the luxury of eating dinner with the backdrop of the Rocky Mountains or waking up to the sunrise over the Sierra Nevadas? Amtrak Guest Rewards is one of the hidden gems of Ultimate Rewards transfer partners. While mainstream travel hacking is all about flying international First Class, slow travel can be quite rewarding as well.
