A boy plays with an inflatable beach toy on the beach in Blackpool, northern England July 24, 2013. British beach resorts, which flourished in the 19th century and earlier, have tempted tourists for years with amusement arcades, fairground rides and cheap and cheerful souvenirs. However, as a 2013 report by the Centre for Social Justice states, many seaside towns suffered as from the 1970s it became cheaper and easier for British tourists to travel abroad. Now, according to the Office for National Statistics, larger seaside towns in England suffer from higher-than-average levels of deprivation compared to the rest of the country. Nevertheless, they do continue to attract holiday makers. Picture taken July 24, 2013. REUTERS/Phil Noble (BRITAIN - Tags: SOCIETY TRAVEL TPX IMAGES OF THE DAY)
