I'm doing it for the first time this year, heading down to Alessandria on the GSA with my son as pillion then getting the motorail back, hop on the Rotterdam ferry back to Hull and then home in time for tea and medals. I'm hoping it works for me as I'm a bit limited on time so am trying to push south as far as I can in the time I have and then just hop on the train back. I found railsavers a bit frustrating to deal with to be honest, and found it best just to phone them and speak to someone.
