Cruises. Sorry, just don't get it at all.
Have you been on one?
My grandparents were always going on them and I just didn't get it. They went on a few Soviet cruise ships during the cold war era, I can remember going with my parents to drop them off at Tilbury docks. One of them was the MS Mikhail Lermontov, which sank whilst on duty in New Zealand, not while they were on it thankfully. I also remember frequently going to Southampton to either collect them or drop them off, the ships were always full of pensioners.
So that was my impression, it's a floating hotel for pensioners.
I get to my late twenties and I'm running a business that's in a trading relationship with a global Japanese firm. They held an annual conference (a free holiday in reality) as a sign of gratitude for trading partners. After enjoying a number of "free holidays" they announce that the next annual trip is a cruise around the Caribbean, my heart sank. I was in two minds whether to go, but to not go would be a sign of disrespect.
It was an unusual vessel, the Wind Star, it's a very sophisticated sailing boat. It turned out awesome, we visited lots of small islands and were able to go to places that normal giant cruise ships couldn't. The ship was hired exclusively, so there was only our party of circa 100 + crew on board.
Spin the clock forward a few more years and it's another cruise. This time it's from New York to Bermuda on the MV Horizon, which is a monster compared to the Wind Star and a totally different experience, it was like being inside a huge floating 5 star hotel. I didn't enjoy it as much as we only had two stops, Hamilton and St. George's. The amount of food consumed by passengers was mind boggling, there's always a buffet in action somewhere. Some of the American passengers were so fat that they couldn't walk around, they had those electric buggies.
I would consider a cruise again, but it's not at the top of my bucket list.
