We recently booked this cruise because the last itinerary change created a lot of availability and they started offering cabins at 40% off to fill the space. When I saw the overnight in Istanbul, I knew that could be changed at any time. Been there before and would like to see more but if it doesn't happen, it won't be a surprise. We're getting to Europe on our own but letting Oceania handle the return, just as Mauibabes said.
Go ahead and make your plans with a reputable company that has a liberal cancellation policy.
