You have a choice of Channel crossings again

Having had to report the demise of Sea France a couple of weeks ago, I can confirm that DFDS are now operating up to 16 crossings per day in each direction between Dover and Dunkirk, and they definitely do carry coaches.

Crossing time is 2 hours, about 30 minutes longer than the Calais ferries take, but if you are heading into Belgium or across to Netherlands or Germany, you will save about 20 minutes driving time each way.
