I'm not sure who this book was written for. At times it's technical enough to be a textbook (and it turns out it's a supplement to the author's online course), and at other times, it seems geared toward those with just an interest in theme parks. A through-line about creating a ride/theme park all but disappears halfway before cropping up at the end. It just feels unfinished, given missing(?) chapters 54-59, numerous proofreading errors, and what seems to be changes in direction and unclear delineations when a new "part" is starting.
That's not to say there's not value in the book - there is! If you or a kid you know is gung-ho on working in the theme park industry's technical side, it's a good primer. Alcorn is definitely authoritative and has expert knowledge, and the last thing it feels like is an ad for his class or his company. The best parts for me were the behind-the-scenes construction stories. Unfortunately, they feel too few and far between. Towards the end, he starts to integrate some of the technical jobs and their tasks into a narrative about building the World of Motion before EPCOT's opening, a method I would've loved to see more of. I think as a theme park fan, I prefer the histories, stories, and criticism of the parks than the technical details, so when the stories were less common, I lost interest.
A friend of mine, with whom I do a YouTube channel called Theme Park Workshop, loaned me this book since it was a pivotal read for him. I'm glad I read it, and I took some things away from it. It just wasn't for me, but there will be people like my friend who read this and it sparks everything.
