Celestyal has kicked off a Black Friday promotion that takes up to 50 percent off selected Mediterranean sailings, with third and fourth passengers sailing free on some departures. The catch, if you can call it that, is timing: new bookings must be made between 16 November and 2 December 2026, and the deal covers 56 departures running from March 2027 through February 2028.

For those new to the line, Celestyal runs smaller ships with itineraries built around ports rather than onboard entertainment — the kind of cruising where you actually spend evenings in places like Santorini or Dubrovnik. That's the pitch from John Diorio, the line's managing director and VP for North America, who framed the sale as a chance to see the Mediterranean for less, whether that's a quick Greek Islands hop or a longer multi-country voyage.

The line-up is broad. On the shorter end, three- and four-night "Iconic Greek Islands" trips on Celestyal Discovery run round-trip from Athens (Lavrio), hitting Mykonos, Kusadasi, Patmos and Santorini, with Rhodes added on the four-night version. At the other end of the scale, the 14-night "Mediterranean Icons" on Celestyal Journey packs in Crete, Santorini, Mykonos, Kefalonia, an overnight in Dubrovnik, Kotor, Bari, Corfu and Katakolo.

There's plenty beyond Greece, too. A seven-night "Mediterranean Splendor" sails from Barcelona (Tarragona) to Malaga, Gibraltar, Casablanca, Cadiz and Lisbon, while the 14-night "Mediterranean Odyssey" extends that western loop with overnights in Lisbon and Barcelona plus Tangier, Valencia, Palma and Sète. History buffs might eye the seven-night "Mediterranean Mosaic: Egypt & Turkey," which overnights in Alexandria and calls at Limassol, Rhodes and Istanbul, or the 14-night "Three Continents Explorer" adding Thessaloniki, Volos and Heraklion.

Greek classics feature heavily throughout: "Idyllic Greece" offers a week from Athens with an overnight in Mykonos and stops in Kusadasi, Rhodes, Crete, Santorini and Milos, while "Heavenly Greece, Italy & Croatia" adds a Dubrovnik overnight plus Kotor, Bari, Corfu and Katakolo. An eight-night "Mediterranean Rivieras" sailing links Athens with Messina, Naples, Civitavecchia, Nice and Barcelona.

Why does this matter for travellers? Celestyal's fares are already among the more accessible ways to cruise the Greek Islands, and a 50 percent cut plus free extra berths makes a family or two-couple trip notably cheaper per head. The booking window is tight, but sailing dates stretch across a full year — including shoulder-season months when the Mediterranean is cooler, quieter and cheaper on land. If you've been waiting for a nudge to book a 2027 Greek or western Med cruise, this is a solid one.
