Query: Just buy the standard Unofficial Guide

This book is not really worth buying. I hadn't been to Disney World in many years, and was planning my first trip as an adult (with my friends) and thought that this book would be useful as a supplement to the standard Unofficial Guide. If you just buy this guide for Adults, it is missing a lot of the robust information that is in the Unofficial Guide, so you don't get a lot of the advice and detail that you get in the standard book. Instead, this basically just has summaries of what is in the standard guide -- it doesn't even have any new, unique information. This was a waste of money.
