My partner and I have literally just come back from a cruise to the Fjords on Arcadia and both of us are mid 30s in age. I can admit we had some doubts before going and about age ranges on board and actually this was confirmed once on board, I think aside from a couple of people we were by far the youngest on the ship.
However, I can honestly say whilst there is a limit to the entertainment for people of our age we had a fantastic time. The ship was spotless, the crew in all departments were always helpful, polite and efficient, the destinations were beautiful, the food was good (East was fantastic!) and we are going to miss being on board!!
Our cabin steward Nora was fantastic and really made our trip extra special in the way she made up our cabin and just how interested she was in what we were doing and we had a great laugh!!
