I tried the $115 service that lets you fall asleep in LA and wake up in San Francisco, and it blew me away

Someday, I might hail a flying Uber car or climb aboard the Hyperloop for transportation from San Francisco to Los Angeles. In the meantime, a sleepaway bus offers a good alternative.

Founded in 2016, Cabin (formerly known as SleepBus) recently launched a chartered bus service between SF and LA that allows passengers to fall asleep in one city and wake up in the next - for about $100 one-way. The logistics are a no-brainer: Get in, grab a bunk, and snooze.

The flat rate makes it more affordable than flying and potentially more convenient than driving, but only if you can handle the tight quarters and 23 passengers aboard the double-decker bus.

Last weekend, I had the chance to try Cabin on a return trip from LA to SF. Here's how it went.
