This May, Hapag-Lloyd Cruises will offer guests the choice of which ports to call on during a 10-day Istanbul-Athens sailing aboard the Europa 2. Prices start at $5,750 per person.
The cruise line said: "Guests will take the helm and set the course of the cruise by voting democratically. The only fixed ports on the itinerary are the ports of departure and arrival. In addition to the surprise cruise, the first international circus arts festival will also take place onboard this sailing, and German jazz and pop musician Roger Cicero will be performing his songs live."
Christian van Zwamen, captain of the EUROPA 2, will present guests with a list of potential routes and ports, and point out which locations wll have the best weather, said the cruise line.
The guests will then vote to determine their route across Greece and Turkey. There are 20 destinations in the eastern Mediterranean to choose from, including Limenas, Kavala, Samos and Mykonos.
