Thanks
With DFDS the ferries are much less frequent so is you miss one you feel it more BUT they usually are much cheaper.
The Chunnel is more flexible but often a lot more expensive : but also they are really flexible on changing times.
Your key I think is the possibility that you might have to delay a day : this can move you into realms of more flexible tickets or as you say purchase single tickets perhaps at short notice. I would recommend look at what short term singles look like ( by look at prices in the next few days ) as I assume they run a similar model to Easy jet etc where process go up significantly on or around day of purchase.
Like everything else it depends on when you’re planning to travel. I haven’t bought tickets at the port, only beforehand online.
If you’re worried about being late book a later ferry to give yourself the extra time. If you arrive earlier, then you may well be put on a earlier ferry if it’s not fully booked. We’ve had that happen a couple of times for us, once by the skin of our teeth.
Dunkirk adds another half an hour to the ferry journey, but can be a bit cheaper though for us we prefer to save the time rather than a few pounds. You only have a choice between Calais, Dunkirk or the Tunnel - nothing sails from Boulogne these days unfortunately.
If you pay for a flexible return then you can change things around somewhat, but it will cost you more. Here’s DFDS’s info for their flexi fares:
“Free amendments to your booking up until the the time of departure.
Full refund up to 48 hours before travel.
Flexibility to travel up to 72 hours either side of your crossing time, subject to availability.”
Looking at their website flexi fares are £20 more each way than the cheaper ones so you’ll add an extra £40 to whatever you decide to book.
We have travelled pretty much all options/routes (including LeHavre and Dieppe) and really boils down to where you are in your journey and the time. A lunchtime ferry works well if you want to eat, the same is true (for us) of an 7pm ish one.
The Tunnel is very flexible, and is good if traffic is much lighter or heavier than expected - and the turnround is quicker - and journey time less. If you are doing it in a single dash the time saving can be worth the premium. Especially true when coming back.
Exactly. We prefer to leave fairly early morning here (around 5am) so we end up at our UK base around 4-5pm depending on the ferry we get. Others have written here on the forum that they prefer to leave late evening and drive through France overnight to get an early morning ferry which could be an option for you if you’re worried about traffic problems.
It always worth checking the French sites of the operators as they sometimes have vouchers that aren't present on the UK sites e.g for my trip this xmas DFDS.fr had a 20% winter break coupon which brought the price down nicely.
Some ferries have many crossings, others not. We've twice arrived much earlier than expected, then had to sit in the car for 2 hours anyhow because there was no earlier crossing!
