RIO DE JANEIRO, BRAZIL - MAY 01: Workers help construct a hotel with rooms to be available for tourists in time for the 2014 FIFA World Cup in the Cantagalo shanty town, or favela, on May 1, 2014 in Rio de Janeiro. A shortage of hotel beds in Rio has led to demand for alternative housing around the city and many tourists will opt to stay in some of Rio's slums in order to save money. More than 300,000 visitors are expected in Rio where they will compete for 55,000 hotel beds.  (Photo by Mario Tama/Getty Images)
