British Isles, France, Netherlands and Belgium 11-night cruise
Having had more than 35 cruises across several cruise lines (including Holland-America, Celebrity, Royal Caribbean, P&O, Marella and others), this for me was one of the worst.
The quality of main dining-room meals at dinner was poor with a sluggish service to match (often two-and-a-half hours for a three-course serving). So the service was so poor that towards the end of the cruise, I gave up and decided to eat in the buffet!
Very many of the on-board activities seemed aimed at extracting as much money as possible from guests.
And the entertainment was hit-and-miss. A good British magician/illusionist but a less-than-funny comedian.
Edinburgh and Dublin were good destinations, but both involved time-consuming tenders as well as transport from harbour to city centre. Docking at Belfast, too, was a bus or taxi ride from the city centre, or even the Titanic Exhibition (which was one of the highlights of the cruise for me).
