More Details

The light face of cherry timber, a theme that runs throughout the interior, contributes to an ambiance of contemporary elegance. Wherever you look, there is something to admire: the promise of supreme comfort in the large, deep lounge; the generous proportions of the dining area; the amount of storage room will impress even those planning on the longest voyage with a full complement of passengers. It’s those little details that make a big difference – like the high ceiling, and the grab rail that is now recessed into the ceiling…and on the topic of ceilings, press a button and a section folds down to reveal a home for storage items that need to be stowed away. Everything, from the flat screen TV, DVD player and Bose surround sound system to the ice maker and wine cooler, tells you that our standard inclusions set a new standard in luxury cruising.
