Typical, Last night I booked a 6 day crossing (Dover/Calais) for later this month and didn't see this offer until just now. I wonder if it is retrospective. Ah well.
Your dog has a bike? He certainly has no feet
A cycling dog on a ferry? Don't see that very often..
Can I take a dog as a foot passenger or with a bike?
I think this is a BOGOF offer, you need to book a paid trip and then you get the free trip that has to be taken between 7th October 2018 until 17th November 2018
