You raise an interesting point. The misconception may be based on the thought that passengers of the premium cruise lines are perhaps wealthier and hence "snooty". But nothing could be further from the truth. We find that, by far, those of more affluent means tend to be more socially secure, unpretentious and therefore more open and friendly. And there being no formal evenings aboard Oceania can make for a more homogeneous social mix of passengers. Enjoy your cruise aboard Oceania with the thought that social fusion is a two way street.
