If you're traveling between San Francisco and Los Angeles, perhaps the least expensive and most comfortable option is in the back of a bus.
A Sleep Bus, that is.
Since late April, a chartered bus service between the two cities has been bringing people back and forth for just $48 a ride, and the concept is simple: Get in, grab a bunk, and pass out. You fall asleep in one city and wake up in the next.
