In one word: Boring.
As others have mentioned the book lacks organization. It reads like a first time author, or rather like listening to Grandpa telling his stories of back in the old days.
There is really not much of anything regarding Theme Park "Design". Unlike David Younger's "Theme Park Design & The Art of Themed Entertainment" which really gives you a lot of information on how and why parks and rides are designed a certain way, this book merely explains the roles of the various "Engineers". Ok, that might work if you are in HR or upper corporate management, but it falls flat.
One area that failed miserably IMO is the part that says film and video costs are similar and therefore, no one should rely on video and just use film... something along those lines. As a filmmaker myself, I found this completely at odds with reality. Film making using REAL film costs 50x or 100x what it costs to do on video. The video quality in cameras, lenses, and storage capacities of SSD drives makes it possible to exceed any and all of films great uses. AND, the costs to deliver the video images with HD and 4K or better projectors is infinitely cheaper than bulky films with short shelf span. This whole section baffled me.
This is NOT the book to get if you want to seriously learn how or why parks are designed one way or another. My recommendation in a word: skip.
