Many thanks. My only concern is that Oceania's excursions got less than stellar reviews and I'd like to arrange some private tours. The ports are primarily "off the beaten" path - Yalta, Sochi, Russia, Sevastopol, Odessa, Constanta, Romania, Nessebur, Bulgaria, Kusadasi. We've been to Santorini and Athens and I have the name of a guide4 in Istanbul. Does anyone know of private guides in these ports or how I could locate them?
