Most cruise ship and liner books are not specifically meant for model ship building. It's especially evident in the number of books full of photographs, but with little or no hull lines or general arrangement or construction information.
Don't let that deter you though. If you can source a plan from somewhere else many of the picture-heavy books will help you understand details of the ships. Whether it is to find what type of davits used, deck planking width or the shape of those vents. A lot of questions can be figured out from the photos in this type of books.
