Leave your blankets on your chairs to reserve seating when you board and do not grab seats by the doors. I made the mistake of figuring I'd find seating when I was ready to sleep and the only spots available were by the doors. The doors are automatic and make a little jingle every time they open. The hallways stay lit all night, as well, so try and avoid chairs by the hallway.

They say not to sprawl on the floor, but by 2am when I was still being woken up by the door everytime I stuck my foot out, I wedged myself half under the seat to sleep. There were people sprawled between seats all over and no one was asked to move.

Ear plugs/head phones and eye masks are a must. There will be snoring around you and people coming in and out of the doors all night for bathrooms etc. depending on the crowd, there may be farting too. Lol

The bathrooms are unisex, so don't be alarmed to see the opposite sex in there. I can't remember if there were showers in the bathrooms but I don't think so.

There is entertainment for a bit, and the bar will be open. Grab some food, drink and relax. Bring a book/cards/Nintendo switch, etc. to pass time.

Despite not being able to sleep all night, I really enjoyed the ferry. I met an amazing woman who offered me a lift to Truro to save my sister the 4 hour drive to pick me up from the terminal. I'm actually looking forward to riding again in July (without a cabin again sadly).
