My experience with DFDS Ferries when we had to cancel our Dover- Dunkerque ferry for our planned Greece trip earlier this year was very good. They offered to give us a 12 month credit but instead gave us a full refund when requested. When I book again, I will book the return leg on a flexi ticket so I can amend my return date at no or minimal cost. However, Like many others I guess next year I will not be booking ferries and purchasing Travel insurance until we get the green light from all the relevant countries, F.O. etc., at least this time around we know what to expect. Onwards & Upwards.
