The short answer is... not a lot, really. Some drivers do have more appealing personalities, but none of their dialogue reveals anything major about the ride. Kalana, Will, and Doc seem to offer the closest to additional mythology, but none of them impact the overall ride experience save maybe for the beginning and end when there are no screens.
Still, I found it mildly amusing to pursue the full set, and to save time for anyone who might feel the same way, I've put them together all in one post for you.
(The descriptions that preface each video below were pulled from this article.)
Kalana: A mystical descendant of the natives who first settled on the island.
Will Denham: The fresh-faced, adventure-seeking younger cousin of famed movie director Carl Denham.
Jinks Costanza: A hardened New York City ex-con who is wary of the island’s mysteries.
Becky Callahan: The loose-cannon cowgirl who isn’t fazed by the dangers awaiting her on Skull Island.
Charles “Doc” Jordan: A PhD student in paleontology who took time off from his studies to explore the world.
