We are booked in a similar way with our bikes travelling on Eurostar to Brussels in May. We have to take our bikes to drop off 1.5 hours before departure and have been given a map to help us to find it. When booking, I first checked with the baggage that there were two spaces for fully assembled bicycles. I was told there were spaces on the train I wanted to travel on and I then booked the train and got back to baggage. It was all done fairly quickly. Now all we have to do is take the train to Paddington, cycle from Paddington to St. P and get ourselves and our bikes to Belgium where we are touring Brussels - Antwerp - Ghent - Bruges - Brussels. It is Mr Yoyo's first tour. I have done the Danube from Passau - Vienna. I hope you enjoy it, Vernon. It is a very easy cycle and most enjoyable.
