You like traveling? Then why to travel and stay in different hotels when you can actually travel with your hotel.

I have to admit this is one of the best business ideas I have seen for a while. German company Das Rollende Hotel offers budget traveling all over the world in a bus-hotel called Rolling Hotel. Source

The idea is that you actually never leave your hotel, hotel always comes with you. They use specially modified version of Mercedes bus. It can take 24 passengers. All you need is to buy a ticket and start your journey around the world.
