We like all the ships in the Regent fleet (yet to try Grandeur).
Each ship has its plus points and minuses.
Every cruise is slightly different and, as well as the ship, we find our experience to be more influenced by the Regent team, entertainers, fellow guests and weather - none of which can be predicted with certainty in advance.
We tend to choose our cruises based on itinerary and our judgement of value for money; booking and going on all our vacations with a positive attitude.
Maybe this thread should have been titled “What are Mariner’s good & bad points?” rather than “Just how bad is the Mariner?” 🤔
