Are you dreaming about lying down while you are touring a country on a bus? With these cool German buses every passenger can take a nap on a comfortable 6-foot-long bed. Hotel buses, of course, have a bathroom, but no shower. Bus-bed tours are available across Europe, Africa and Asia  since 1959. They are hosted by Rotel Tours where the word “rotel” is a portmanteau of “rolling” and “hotel”. These “beds on wheels” might not be the most comfortable hotels in the world, but they are the only hotels that can take you around the world!
