Are you starting in England and taking a ferry to Hook of Holland?
If so, and you are planning on going back to England, you can take a bike on the night train to Paris, then jump on the Eurostar - the ticket for the whole journey could be bought from Rail Europe though you'd need to pay extra to Eurostar to take a fully assembled bike on the train...
If you live in Hook of Holland then ignore everything I just said...
