Not sure how you were allowed to see a crew cabin on a Carnival U K ship ? And genuinely interested how you did. As crew areas are out of bounds to guests unless you were visiting a crew member on a pre booked day day pass and even then I am not sure you are allowed in the accommodation areas. The cabins too will vary depending on your role on board. My last cabin steward on QM2 was about to retire after 40 years service and he was telling me he was by far not the only one onboard with such long service. Another time my lovely waiter told me he shared a cabin with his wife who was a cabin steward. They had worked for Cunard fo 12 years. I assume if you stay in a job for 40 years it can’t be that awful. If you notice many crew members have fake gems on their White Star or Shine badges denoting 5 10 years service etc.. Many to be seen and I always make a point of asking how many contracts/ years have they done ? There are a few videos on you tube showing crew cabins. Some lines have single cabins but shattered a bathroom. I personally would not want to see their living areas as I see it as an invasion of their privacy. Crew areas are their homes for up to 9 months not an attraction or entertainment opportunity for me. I am sure most regular cruisers on here would not assume crew cabins would be in any way similar in size or amenities to passenger cabins, I don’t stay in hotels but would imagine hotel accommodation for staff is of a similar calibre.
