British reserve is in short supply on New Year's Eve, when 250,000 revelers descend upon central London for a riotous open-air party. Countdown the twelve final chimes alongside Big Ben, and watch the city explode in light and color as fireworks go off over the London Eye and the Thames River. For prime viewing, head to the Victoria Embankment and the Waterloo and Westminster Bridges (the area around the London Eye is cordoned off). Once you've taken in the fireworks, hit the pubs along with scores of other hardy souls, link arms and sing Auld Lang Syne in your best, rowdy, off-key falsetto. If you've decided to spend the evening at one of the West End's fantastic stage shows, you may find yourself cozying up to the stranger next to you to ring in the New Year. It's a tradition on New Year's that come curtain-call, the entire cast and crew come together and get the audience to join in with a rendition of Auld Lang Syne. Festivities don't end on New Year's Eve — so squeeze in a power nap and a traditional breakfast fry-up. Once you've regained your faculties, head to the annual New Year's Day Parade, a three-hour extravaganza featuring up to 10,000 performers from around the globe.
