I have traveled between Amsterdam and London by Eurostar and by plane, and I don't see why anyone would take the train, considering that it takes much longer and also costs much more.<p>To put some numbers to this, if I were to travel to London on December 13th (a Wednesday), I'm looking at 120 euro for a five hour trip by train. Or I can fly for 76 euro and be there in an hour.<p>Oh, and the train also requires you to be there an hour early, so you don't get the advantage of showing up late either.
