(Note: this picture is from the website; I did not take it. There's never really a chance at this angle even when you aren't on the ship.)
She was built in Finland and her maiden voyage was December 5, 2009. In order to get out of the shipyard she had to go under a bridge that she was just a bit too tall for. In order to solve the problem they made her smokestacks retractable (just for this one bridge, they never need to retract again!) and went at the bridge full speed (just under 24 knots or 27.63 miles per hour), in order to get as low in the water as possible. They barely squeaked under!
She has props of a new design that can swivel/turn 360 degrees, so that she can literally turn in place!
She is one of the two largest cruise ships in the world (the other is her sister Oasis Class ship, Allure of the Seas [Allure is actually 2 inches longer, technically speaking...]) at 360 meters long (1,187 feet), 64 meters wide (208 feet), 65 meters above the waterline (213 feet), and a draft of about 9 meters (around 30 feet). She weighs in at 2225, 282 tons (out of water)!
She has 16 public decks and 2706 guest rooms which can hold up to 6300 guests. The staff hovers at around 2300 and during my cruise they represented 64 countries.
It has a zipline, 2 rock climbing walls, 2 flow-riders, 24 dining rooms, restaurants, et cetera, about 12,000 plants and trees including an onboard park, several theaters (live, movie, and aqua!), a boardwalk with a carousel, an ice skating rink (smaller than standard at 40 by 60 feet), a promenade, several pools and hot tubs... pretty much anything!
It was an absolutely amazing week!
