This is THE book on Walt Disney World. If you're thinking of having a holiday there in the next 12 to 18 months, I want the most for your time and your money, this is an essential book for you.
For me, the best thing about this book are the Touring Plans, a step-by-step guide on how to efficiently see everything the Park with minimal wait. The book's authors claim that this can save you four hours waiting in line a day, and after using them, I have no doubt about it. The least liked Touring Plan, for the Studios, has now been totally rewritten with less backtracing. Of course, everything else about Walt Disney World is also in here, from reviews of all restaurants and attractions to how long you should expect to take to get to each Park from your resort.
The style of the book is serious when necessary, but usually a lighter tone makes reading it enjoyable. Each year around 100 pages are updated in line with changes at WDW. New inclusions in this 2013 edition include: updates on FASTPASS Plus and the mobile app "Lines"; reviews to the new "Art of Animation" resort and 20 off-site resorts, together with substantial changes to the Downtown Disney hotels; how to get cheap(er) hotel rooms; New Fantasyland and Sorcerers of the Magic Kingdom; where to get last minute Dining Reservations (ADRs). Updates to this book can be found on the TouringPlans website, and more helpful planning advice can be heard on the WDW Today podcast. Basically, for the price it is, a must buy.
