Nowhere on earth does nightlife like Las Vegas, and the biggest celebration of the year sees over 300,000 people descend on the party capital. The famed Las Vegas Strip is car-free and firework-friendly throughout the night, with live bands, pyrotechnic displays and laser-shows turning the area into a giant street party. Bars and nightclubs all over town will be turning up the volume (and the ticket prices) for some mammoth celebrations and famous music acts will be hitting the stage (The Killers, The Red Hot Chili Peppers, Pitbull and Calvin Harris are all on the bill for the 2013 celebration). Whether you're gambling away the past year's savings, smooching beneath Bellagio's famous dancing fountains or partying into the early hours in a haze of champagne cocktails, Vegas does its hard-partying reputation proud over the New Year.
