I was really disappointed that I could not find and Ashford / Folkestone to Calais / Bologne bus link or way for people without vehicles to make the short crossing at one point. Good that P&O have resumed accepting foot passengers on 3 services a day. Asking for Ashford to places on the continent, Google suggested I change trains at St Pancras!
I have used Harwich / Hook, but not since the train service at Hoek became a metro. The overnight crossing is a good (if not cheap with a bed) starter - from Melksham mid afternoon - sleep on the ship, and then off to Utrect or Venlo and onwards to Frankfurt, Nurnberg, Aalborg or Thun - all of which I have done.
If the service at Hoek is a metro, presumably Interrail tickets wouldn't be accepted on it?
We are aiming to do our first interrail trip this spring, so it would be useful to know, in case we decide to head out or back that way.
