DFDS Seaways

Do not use for taking your dog on vacation.
The website specifically advertises dog-​friendly crossing to Europe. The conditions are disgusting, nothing is organized, and your dog will be traumatized.
The «kennels» consist of two disgusting cages shoved in a small hole by the trucks. I was not able to visit or care for my dog during the journey because the crew simply could not be bothered to escort me, which is required to go to the truck level.
At disembarkation, the crew had no consistent policy. I was told by the information desk clerk I was not allowed to take my dog off the boat and that someone would drive me back on to get her. Then at the shore office, I was told someone with the crew would collect her with the luggage. Finally, when the very rude station manager brought her off the boat, he lectured me that I shouldn’t be taking my dog on boats. Seriously?!
TL, DR: if you care about your dog, use Stena Line and go through Holland instead

We’ve come here twice for the cheap weekend away to Amsterdam from Port of Tyne. This time we drove and found the car park (kind of) easily, parked up and were ready to check in!
We unfortunately managed to choose the SLOWEST queue in the world so ended up taking ages to check in which is annoying– please sort this!
Once we got on the ferry however we loved it, just like before. Our seaview cabin, our all you can eat buffet, the views. Everything was brilliant. Staff are all happy to help and polite and everything is well organised.
Make sure when you get off at Amsterdam that you are first in the queue as once the coaches are full they set off for Amsterdam, so the quicker you get off the more time you get in the Dam!
We took advantage of the 2 for 1 £85 for 2 people to Amsterdam deal which is such good value for money.
To leave my car in the port of tyne for 2 days for only £24 which I think is really reasonable.
Will always come back for some mini breaks :)

Parking on board not for the faint hearted. Very little space between the vehicles parking on a slope. So much so that my car got scratched by other people squeezing passed. On board the cabin was fine, a double bed room with a shower cell and a sea view. Drinks are on a par with inner city bars but the cocktails were rather small. I did however get a card from the captain inviting me to 2 free drinks. Not sure why but gratefully received. Breakfast buffet was a mix between english and continental. English was not that good. Bacon and sausages were overcooked and dry. The eggs were powdered.
