I picked up this book last week. And while I've been mostly pleased with it, I'm a little disappointed with some of the mistakes that are in it. I won't go into detail, but just say that some ride descriptions need to be updated since the refurbs happened two years ago. And another ride is relegated to a quick mention at the end of the chapter and not even included in the descriptions of rides in its land (and it's been open for two years).
Also, the rat in Ratatouille is named REMY, not Ratatouille. I know that some other things were wrong, or not updated.
Again, just a few mistakes, but enough for me to be disappointed that things were not more accurate.
Other than the mistakes, I think it's a great read.
