I felt the same way before our first O cruise on Insignia in September 2022. I thought I had made a mistake after reading all of the negative comments on CC about the decline in food quality, lack of energy, etc.
We had a fantastic cruise and thoroughly enjoyed the food as compared to our previous cruises on Azamara & Celebrity. We enjoyed ourselves enough that we are sailing on Regatta this September. While I have some concern about the recent negative comments, I have to remind myself of the negative comments back then as well.
Like others have said, go into your cruise with an open mind.
