I need to get from London to Rome. I know there are direct flights, but, I wanted to take the opportunity to do a boat trip along the way.
My general plan was taking a train from London to Dover, then a boat to Calais or Dunkerque, then a train to some airport in France, then a plane to Rome. But, I did not find an appropriate airport in France for this plan - all airports I checked required 3 of 4 trains and a very long land journey, which I would like to avoid.
So, my question is: what is the way to do this trip, with the least land-travel?
