The world's largest, highest and tallest
You'd have to run the length of nearly three and a half American football fields before you made it from bow to stern of Royal Caribbean's Wonder of the Seas, the world's largest cruise ship.
The 18-deck behemoth, complete with its own zip line and what's billed as "the tallest slide at sea," will set off on its maiden voyage from Fort Lauderdale, Florida, to the Caribbean on March 4.
Also on the "wow, that's high" front, Heavenly Jin restaurant on the 120th floor of the Shanghai Tower -- about 1.5 times the height of the Empire State Building -- has just been named the world's highest restaurant in a building.
Meanwhile in Australia, Four Seasons Melbourne is set to open in a skyscraper complex featuring the world's tallest vertical garden. Imagine a garden path twice as long as New York's High Line meandering up the facades of two twisting towers.
