I took the Ocean Tokyu Ferry from Tokyo to Fukuoka

I rode the Ocean Tokyu Ferry with my car, which connects Ariake Port in Tokyo to Shinmoji Port in Fukuoka Prefecture in 32 hours one way.
This time, I boarded a ferry called "Dogo" for 2 nights and 3 days in a private room for 2 people.
The total cost was 53,790 yen, including 35,300 yen for transportation of a light vehicle, 13,600 yen for a private room for 2 people, and 4,890 yen for consumption tax.
I'm a nervous person, and at times like this I usually can't sleep unless I'm in a private room.
I didn't have any particular complaints about the size of the room, but since I had chosen a private room, I felt like I wanted at least a toilet in the room.
Also, there did not seem to be a restaurant on this ship, but instead there were many vending machines with food, sweets, snacks, ice cream, and other amenities.
