The idea came from a company based in Antwerp, Belgium, which baptized Sleeping Around( just to give you a clue). This is not to sleep in caravan which moves around the city, but in a temporary container converted into a hotel, which opens into a different place for each guest.
The large metal containers have been transformed into a stylish hotel, re-designed with eco-friendly materials, so as to provide, in addition to the bedroom, a bathroom and a place for lunch. Rather than staying in a particular location, these giant “boxes” are transported around Antwerp and guests who book one night at the hotel, should be amenable to a kind of treasure hunt. In fact, after you have confirmed your stay you must find a hotel, with the GPS directions provided by the hotel.
