The concept of Hospitality Services, also known as “accommodation sharing”, “hospitality exchange”, and “home stay networks”, refers to centrally organized
social networks of individuals who trade accommodation without monetary exchange. While this concept could also include house swapping or even time share plans, it has come to be associated mostly with travelers and tourists staying with one another free of charge. Since the 1990s, these services have increasingly moved away from using printed catalogs and phone trees to connect users towards Internet websites. These have grown exponentially since 2000 and as of
March,
2007 over 500,000 people are registered users of these networks. These vary in operational structure, place different emphasis on graphical vs. textual formatting, and cater disproportionately to specific geographic regions.
