$1000 of free shore excursions

The discounts apply for cruises from now until August, and as an added bonus there will be free shore excursions to the value of $1000 per couple.

These can include the ruins on Delos - according to Greek mythology the birthplace of Apollo - the palace of Knossos the capital of Minoan Crete, and walking tours of ports and historic sites.

The voyage is aboard the MY Harmony G, which has only 21 cabins but is large enough to have spacious social areas.

Sailing on a round-trip cruise from Athens, the itinerary includes port visits to some of the lesser-known Greek islands, hidden gems such as the medieval Monemvasia on the east coast of the Peloponnese, Kea, Rethymnon, Hydra and Nafplion, as well as the famous islands of Santorini and Mykonos.

The yacht will drop anchor in many secluded bays so passengers can enjoy a dip in the warm waters.

The cruise is now priced from $2835 per person twin share in a category C cabin and $3395 in the higher category, a saving of $1250 per person including the free shore excursions.

This includes two meals a day and use of fishing and snorkelling equipment.

The special offer is for departures on June 23, July 7, 21, 28, and August 4, 25, and is valid until sold out.
