These submarines are truly state of the art and were produced at a cost of millions and millions of dollars. I think that they’re greatest attribute is that they give people, and especially children, a likely first glimpse of a world that lives in a completely different universe than the one we are used to seeing. When the submarine comes back up, that world is still down there and intuitively everyone, particularly children, retain this memory and this expands their vision of the reality of the world around them. This is one of the great tours we have on the island for children of all ages, yourself included.
The one thing you need to remember is that no-one will be permitted on the sub unless that person is over 36″ tall. For children shorter than this, the glass bottom boat would provide a similar experience.
