Dubai is a city that revels in superlatives: the biggest, the best, the richest, the newest, the most luxurious and the most expensive are all adjectives that really matter in the desert metropolis. In light of its breathless and relentless race to become the hottest destination on Earth-having hosted some 12 million tourists this year, it was the fifth most-visited city in 2014, behind stalwarts including London and Paris and ahead of New York-it's no surprise that New Year's Eve is a very big deal in Dubai.
