Be careful here - you don't "just turn up". You arrive without a ticket then have to find the reception and lock the bike somewhere outside, queue, hand over passport, pay etc etc. Then ride bike out of reception area and get in the queue to check in. Far better even to have the app on your phone and buy a ticket that morning, and arrive with the barcode showing on the phone, and go straight to the queue to get on the boat.just turning up
I did this "just turn up without a ticket" at Dunkirk and a £22 fare became €40 plus it took ages to do.
