I bought 12 return multi-trip tickets on Norfolkline
ferries Dover-Dunquerque last spring at £38 return each.
This is a marvellous deal and I recommend it to anyone who is a frequent traveller to France as an alternative to P&O and Seafrance, and I intend to buy a further 12 for next year. The tickets are fully flexible, you can travel at any time of the day and book/cancel your crossing time right up until the last minute. You can also transfer the tickets to friends/family at no cost! Norfolkline have 3 new ferries on the route, and the fact that they do not allow coaches or foot passengers makes the crossings much more enjoyable (no booze-cruisers or packs of rowdy teenagers on school trips).
The only problem is, I have one return crossing left, which has to be used by 17th December 2009. Does anyone want it? I am able to transfer it to anyone else's name, at no extra cost. Please let me know if you are interested and I can contact you with more information.
