Doesn't matter which ship you take on Oceania; some people prefer the larger (1250 passengers), other the smaller (650 passengers), but always first class service and food. None of this comes inexpensively, so what's to complain about?
There were a lot of families with kids on this cruise. Whoooops, not much for kids to do on Oceania. Someone gave them bad advice to take this line, it is geared to 50 somethings and above IMHO.
Food and service were excellent. I don't understand Sue Traveller's criticism, but each to their own. (Don't understand her complaint that she could not book more meals in the specialty restaurants, people were doing it on a space available basis once all had a chance to book the restaurants.)
