The United Nations Environment Programme (UNEP) cites that in most all-inclusive mass tourism package tours, about 80% of travelers’ expenditures go to the airlines, hotels, and other international companies (who often have their headquarters in the travelers’ home countries), and not to local businesses or workers. Of each USD 100 spent on a vacation tour by a tourist from a developed country, only around USD 5 actually stays in a developing destination’s economy.
