Rotterdam is a sister shop to Amsterdam. It sails on world cruises and extended voyages. One of the most traditional ships in the fleet, Rotterdam interiors display abundant wood appointments in the public areas on Promenade and Lower Promenade decks. There is also priceless art throughout. The Ocean Bar, Explorer's Lounge, Java Café, Wajang Theater, and Crow's Nest are familiar lounges to longtime Holland American passengers. Newer additions are a thermal suite in the spa, a culinary-arts demonstration center in the theater, and expansive areas for children and teens.
