It is our first time to go. We are a couple (28 years old) without children and we need to see as mush as we can in 4 days only. I heard about The Unofficial guide & The complete guide to Disney and also some others, We have time to read only one book. We prefer also detailed maps and directions.
I'd say it's a tossup between the Passporter and the Unofficial Guide.
-You can write in the book and plan… also keeps stuff
-Awesome maps! Colored, detailed, shows time to walk from one place to another
-Nice data about rides and attractions
-Some touring plans
-LOTS of information
-Many great touring plans
-Includes info about nearby hotels, restaurants, and attractions
Really, I'd get both books and skim through them. You don't have to actually read them- just look at the parts you need.
