Gringotts is one of those rides that grows on me. The first time I rode it, and everything worked except the water effect, I would have given it a 7. By the fourth or fifth ride, my rating went up to a 9 or 10. There's so much happening, and things to see, you don't notice everything during the first runs. While I rate FJ as a better attraction, I actually have more fun riding Gringotts, primarily because it's less intense, therefore I can repeat ride it more. I've now rode Gringotts well over 2 dozen times. I suspect Kong will be the same to me. I'll notice more and appreciate it more with repeat rides..... A point I've brought up here many times before, but I believe it's probably pertinent here. Disney Imagineering great Tony Baxter, in interviews has said, it's important to design an attraction where it's actually better on the 20th ride than the first. That a great ride will have you notice & experience more nuances the more times you ride......
