Yes, they have indeed, but only those to ME ports in countries in the vicinity of this terrible conflict. We have been following threads closely, because we and our fellow Canberran friends are booked on Oceania Vista's three-weeks Med April '24 cruise. Turkey is the only destination we are wary of at the moment, especially as their President was whipping up the crowds in Istanbul overnight (our time) with inflammatory and threatening calls. We were looking forward so much to the deeply meaningful experience of sailing the Dardanelles on Anzac eve, and overnight in Istanbul, but it would seem to be a doubtful stop, at this stage. Five months is a long time in cruising, so we'll watch and wait. We have spent many weeks in Turkey a few years ago, but our friends have never been.
