KRAUSNICK, GERMANY – FEBRUARY 15: A couple from the east German city of Chemnitz lounge with their son at the “South Sea” beach at the Tropical Islands indoor resort on February 15, 2013 in Krausnick, Germany. Located on the site of a former Soviet military air base, the resort occupies a hangar built originally to house airships designed to haul long-distance cargo. Tropical Islands opened to the public in 2004 and offers visitors a tropical getaway complete with exotic flora and fauna, a beach, lagoon, restaurants, water slide, evening shows, sauna, adventure park and overnights stays ranging from rudimentary to luxury. The hangar, which is 360 metres long, 210 metres wide and 107 metres high, is tall enough to enclose the Statue of Liberty. (Photo by Sean Gallup/Getty Images)
