Many of the major cruise lines started to release new itineraries for the upcoming season, with Holland America Line (HAL) being one of them. The company revised their Mediterranean itineraries for 2016, though this counts just for ms Eurodam and ms Oosterdam starting April through October next year.
You can already book these new 2016, HAL Mediterranean cruises, and you'll notice that the line has added a couple of back-to-back 7-day voyages in the months mentioned above.
As an added incentive, the company promotes some extra savings, as part of its Explore 4 promotion. Better hurry up, as this particular promotion ends on 31 October, which is next Saturday.
