Good general info but...
It needs maps! There is a scarcity of images to know if youre at the right location. Which rides are Fastpass... where are restrooms... are there shortcuts?
Another big omission is dining. No information on even the theme parks restaurants, much those at the resorts.
For .99, I guess theres enough general information to be helpful. As a complete Disney World guide, however, Id search for better apps.
