Since the advent of the Channel Tunnel, (aka Chunnel) you can get on a train in Central London and emerge about 3 hours later in the centre of Paris. For this reason alone, Paris, Brussels and Lille (and any other connecting French or Belgian station) have been brought a whole lot nearer London. Taking the train to the mainland feels decadent and nostalgic, like the golden age of steam, but with a much faster and quieter mode. Where once air travel felt luxurious, now it's train travel that adds that certain je ne sais quoi. Don your favourite threads, pack a hamper of bubbly and nibbles, and you'll be browsing the Marais and romancing the night away, Paris-style, before you know it.
