World’s largest cruise liner has a twin

HELSINKI -- The second in a pair of the largest cruise liners in the world - an extravagant behemoth spanning nearly four football fields, with a 3-D move theater, an open-air central park and room for 8,300 people - set sail Friday for its new home port in Florida. The Allure of the Seas, which cruised out of the shipyard in Finland, faces its first big test Saturday, when it must squeeze under a Danish bridge, just one foot taller than the ship - even after its telescopic smokestacks are lowered.
