Two votes here FOR O's shower doors, we found them better than AZ's shower curtains. Also, O's R class cabin re-fit has been superbly done, more storage space and lighter décor. However, this does come at a price which we now consider does not represent value, so we'll stick with AZ as far as we can, desirability of itineraries to take into consideration. We wish they had fewer embarks and debarks in Istanbul and Athens.
