I think we can all agree ... this is a serious case of "backstory fail".
I have a feeling that for budgetary reasons they decided to install off-the-shelf rides and carny games ... then worked backwards from there to come up with a backstory that would relate their budget limitations to some kind of theme. Meet Chester and Hester.
The story of Jurassic Park is perfect ... completely logical and easy to understand. So come up with another simple, logical story. Like, this is the Land That Time Forgot, a hidden, unexplored corner of the world where dinosaurs still exist. Or, this is a really classy update of Dinosaur National Monument with the latest in cool transportation technology for exploring the fossil deposits ... fossil mine trains, advanced time travel centrifuges (spinner ride) and so on. Either magical, technologically cool, or both. Not tacky.
The Dinosaur ride itself has a story that is utterly un-engaging. The character who sets up the dinosaur snatch is completely unsympathetic. And it's just an actor on a video screen anyways, and then a voice coming from a speaker somewhere in the ceiling in the middle of the ride. How? Why? Who would travel back millions of years to the exact time when a giant meteor is coming? You're supposed to grab a dinosaur and bring him home ... What dinosaur? Catch him how? Carry him where? Nothing makes any sense.
Not to mention that the illusion of traveling back in time, driving a jeep through a rain forest, seeing living dinosaurs and then witnessing a gigantic meteor shower is literally nil.
I'll forgive Disney because they came up with a really wonderful, if incomplete, animal-based theme park. But somebody was really phoning it in from Burbank when they came up with Dino Land.
