I have only been to St. Kitts once, and being a fan of trains I took the tour that includes the sugar train. It is only sold through the cruise line. It is in two parts: half in on small buses and circles half of the island. The second part is on the train. The bus part stops se era, places and I believe there was narration. The train is double decker. The lower level is enclosed and has tables and chairs that will accommodate everyone, and a restroom. A spiral staircase takes you to the upper level which is open air and has benches all around. They mixed a punch and passed it around, or you could have sodas.
I took the afternoon tour that did the bus part first. There is a bus for each car of the train. If you are in the first bus, you will be in the first car. I was slow, so in the last bus and last car. I loved it. It’s narrow gauge and sways a lot, so goes really slow. I loved watching the countryside and little villages. The buses stopped in a large field with train tracks, we got out and waited. The train came, the folks on the early tour got off and boarded the buses we had just left, and we boarded the train. EM
