We just got off the Ocean Odyssey last Saturday in Athens. Our experience onboard was good. I found the staff to be helpful and very friendly. Our cabin was #434...by the Zodiac storage area. Since none of our ports used the Zodiacs we were never bothered by any noise. This cabin was fine, and I wouldn't hesitate to choose it again. We, too, were victims of our flight reservations being cancelled due to non-payment in a timely manner by Vantage. We had prem. economy...lost the seats we wanted...but just kept watching the United website to see if seats we liked better opened up. They did. All in all, it was a great trip!! I am not sure I would ever book Vantage again due to their HORRIBLE (or lack of) customer service. Sad..They are their own worst enemies!
