Part 2 starts at 11 p.m., when I board my Cabin in Santa Monica. The ground floor has table seating, kind of like the dining car in a train. The upper level, however, is like nothing I've ever seen before. On each side of the walkway, there are beds — several across, and stacked in two like bunk beds, only built into the bus.

They're called pods, and crawling into one is jarring. It's not high enough to sit up in, so you have to crawl. And once inside, it feels like being in a cabinet or a coffin (you pick). I inch my way into a top pod, trying not to make noise because a mother and her little girl are sharing the pod below me...

When we pull into a parking lot in San Francisco, I realize I've been out 7.5 hours (way more than usual)... You may be wondering how I slept for so long, since LA to San Francisco is only a six-hour drive. Well, to guarantee a full night's rest, the creators of Cabin turned it into eight hours — by driving slower and using back roads.
