I can understand your point, but most of these problems exist throughout the industry both on ships and on land. I would list the following; the need to step up into the bathroom (I guess this is due to the need for space for the pipes, but it is easy to miss the step in the middle of the night), the seating is too low except for the dining areas (I find it difficult to get u from a seat where my knees at an angle greater that ninety degrees).
