I think the vast amount of resources used on these ships is simply a manifestation of a culture of exploitation. How can so few have so much? And now a library is being added as bait. Justification for the exploitation of cruise workers and destruction of the environment can't be done by adding a few books to spiff things up.
CNW group reports "Queen Victoria will not only be a classic ocean liner...she will also feature some exciting innovations. These will include the first private boxes at sea, in the Royal Court Theatre; a "Cunardia" museum, housing Cunard artifacts and memorabilia; the first two-story library at sea, with its 6,000 books and splendid spiral staircase;and a grand, British colonial-style conservatory, complete with central fountain, greenery and a retractable glass roof."
