London, United Kingdom
To put it simply, London is like the New York City of Europe...sort of. Nothing can really be compared to London. It is a business and culture hub, that has hosted the epic historical events, and was once the super power in Europe and the World. London is not one of those cities you can see in a weekend, I tried. You need at least a week to just scratch the surface of what is London. Retrace history, and don't forget the great night life, making it a great place for anyone to visit.
Popular Attractions: The London Eye, Buckingham Palace, The Tower of London, Platform 9 3/4

Tips: the underground and trains are confusing, carry a map, but don't be afraid to get lost.
