Leaving behind the maritime heritage of the UK, prepare to be dazzled by medieval Antwerp, Europe’s premier diamond hub (ideal if you have a certain question for a certain someone in mind), before moving on to vibrant Rotterdam, the Netherlands’ second-largest city with a lively vibe and fascinating food scene. Then we come to Hamburg, as artsy as Berlin but with a more lowkey vibe; enjoy two days of exploring its museums, architecture and cool cafes. A day at sea brings a chance to enjoy the onboard spa and restaurants before we arrive in Oslo, the Norwegian capital. Then we come to Denmark for two days in the fairytale city of Copenhagen, soaking up its cosmopolitan cool, and historic palaces, castles and churches.
