I chose this cruise based on the destinations and more importantly on the recommendation of previous Oceania cruisers. The ship was fine although it seemed to be ready for refurbishing.
The food was okay, but not as special as I had anticipated. Desserts were the most disappointing aspect of the food train. They seemed bland and unimaginative. I heard several complaints about the lack of or taste of the "chocolate" desserts. The behind the counter servers in the buffet area were attentive and accommodating, but the wait staff (coffee and incidentals) in that area were somewhat less so. Service and accommodation in the main dinning room was first rate. Food and service in both of the specialty restaurants was first rate.
The entertainment on board was very good. We greatly enjoyed the young performers. Interacting with the cruise director, Julie, was a treat.
Room attendants and their service was excellent. The entire ship's company with exceptions noted were very responsive. Midway through the cruise we filled out a questionnaire critiquing our experience. Almost all issues we noted were addressed within 24 hours. Once the response was simply an explanation of why things were as they were, but they did get back to us on the issues.
Largest single disappointment in the cruise was the inconsistency of the shore excursions. Some were good to excellent and others were not so much. This seemed to result from lack of proper planning on the tour operator's (management) part and perhaps not so much on the individual tour guides.
Overall I considered the cruise a success and would do it again.
