First of all let me say that my wife and I are fairly experienced cruisers and so have plenty of points of comparison.
Negatives - Announcements in five languages. Fairly short time allowed in port.
We were aware of both these before we travelled and so they came as no great surprise. In any event the announcements were only made about three times a day and soon ceased to intrude. The amount of time in port is, to a large extent governed by the itinerary and as the destinations were a major factor in our choice of cruise this criticism is also tempered with pragmatism.
