Holland America Line
has invested over $425 million (£207 million) into enhancing its ships' facilities as part of the Signature of Excellence programme.
Originally announced in November 2003 as a $225 million project, the cruise line has devoted an additional $200 million to improve its ships' activities and amenities.
Among the aspects of the ships to be improved for passengers enjoying family cruises
are the Culinary Arts Centre - a modern show kitchen featuring guest chefs offering cooking demonstrations as well as teens-only activity areas.
Other additions to the Holland America Line
flotilla include flat-panel television sets, make-up mirrors, high-thread-count linens and deluxe bathrobes.
"Signature of Excellence began as a ground-breaking initiative within the cruise industry. At Holland America it has since evolved into our brand promise and our company's commitment to continually invest in our product," commented Richard D Meadows, Executive Vice-President of Marketing, Sales and Guest Programmes.
Meanwhile, the cruise line's ships have not been the only element of the company to receive upgrades as Holland America Line's
private Bahamian island Half Moon Cay has benefited from new shore activities such as horse riding.
