In my first marriage, I experienced about a dozen cruises, including one where we treated our widowed Mums to one to the Norwegian fjords. They loved it! My favourite was to Alaska.
My second husband was adamant that he wouldn’t like cruising but was tempted by a Fred Olsen one to the Christmas Markets, mainly because it included the Kiel Canal. Sadly, that was shrouded in fog but he was hooked. Since then we have also visited Norway, Baltic capitals and France, mainly by river, all with Fred Olsen.
We like the opportunity to visit new places without having to drive or pack/unpack or cook and we enjoy the port lectures and live entertainment. At times, we pursue different activities on board, sometimes separately. Depending on the place, we explore independently or on an excursion.
I abhor the mistreatment of staff in any workplace but whenever we’ve been ashore, several members of staff also had time to explore the port of call. Yes, pollution is a concern but then flying and driving aren’t entirely kind to the planet either. I was impressed to learn (admittedly in 1996) that Princess Cruises donated redundant mattresses, etc to the needy in some of their destinations.
It amuses me how strongly the non-cruisers feel about cruises. I’m not interested in skiing or beach holidays but understand that others love those. We aren’t all the same - that’s what makes life interesting!
