The line said the intervention was "the biggest refresh" of its schedule in the region "in a long time", one that will see it add several new itineraries combining regions.
It will also offer additional 14-day or longer itineraries, including dozens of "unique itineraries". Pinnacle-class ships Nieuw Statendam and Rotterdam will sail many of these new departures between April and November, which range from seven to 35 days.
Along with Oosterdam and Zuiderdam, HAL will station four ships in Europe in summer 2024, utilising nine overnight ports and offering 33 late-night city departures to maximise shore time.
