Had 3 nights from southampton to Paris, Brugge and back to southampton.
Boarding was a breeze, left lugguage outside with staff and given a tag, went inside answered a few questions had a picture taken while sat down and boarded. Took all of 10 minutes. They were not strict with boarding times.
Could not go to room until 1pm but could use drink package as soon as you get on board so that was fine. Room was the usual balcony version all nice enough.
Nice cabin, has most thing you would expect.
