The operator will offer two new itineraries; a three-day cruise, which starts in Athens before sailing to Santorini and Mykonos, and a four-day itinerary, which will follow the same initial route but also take in Rhodes.
Michael Vinales, managing director of Olympic Holidays, said: "Following the successful launch and huge appetite we’re seeing for our island-hopping experiences, our two new cruise itineraries offer guests an alternative way to set sail and explore.
