I would love to get DS that book (He will be 7 (barely) when we're there), but it has too much information on it. The fact the book labels some rides "dark" and/or "scary" would make him not go on any of those rides, even though I know he would love the ride. (He's the same way with some children's movies).
If anyone knows of another guide book whose target audience is kids, I would love to know it.
