If you haven’t booked your trip yet, you may be able to use my Brittany ferries members card as a guest.
This will entitle you to some kind of discount. Card No. F6M621 . Good luck with this sorry it’s a bit late.
That worked for me thanks Les. Got about 10% discount which is not as good as the event offering of 20% but does allow bookings outside of the event window + allows for vehicles not covered by the event offering + only requires a deposit at this stage. I assume you can also amend the booking without a £25 surcharge which appears to be the case with the event offering.
