Even though The Luxury Guide to Walt Disney World Resort isn’t about special diets at the Disney parks, I believe that it can be an excellent resource for those seeking gluten-free dining at WDW. It does an excellent job of describing and reviewing the restaurants available at WDW (Epcot, etc), with an emphasis on the higher-end restaurants, rather then grab-a-quick-bite-to-eat ones.   If you’re planning to make your gluten-free dining a large part of your WDW park experience, this book will allow you to get the most out of your experience by helping you to decide which restaurants most appeal to you.  It’s well worth it.

The book also does an excellent job reviewing the higher-end Disney hotel properties.  That’s not really my thing [because we don't spend much time inside the room], but if that’s your style, you won’t find a better resource than this.  The author’s website has Walt Disney World and Orlando restaurant menus, articles about WDW and Orlando dining, and a lot of other useful information.
