I guess at the end of the day we are reading the ‘opinions’ of a tiny number, not even a handful, of people who were actually on the cruise. If there were maybe 10 who agreed with the OP there were still maybe 600+ who haven’t expressed an opinion here.
My advice to anybody yet to take their first cruise with Oceania, or any other line for that matter, who has been put off by these posts, is to go with an open mind. If you go with the mindset that a, b or c are going to be really bad then … self fulfilling prophecy … they will be!!!
