I was just wondering if any of you experienced planners still read or purchase any of the Disney guidebooks out there? If you do which ones do you use and why? I have been four times now and have read up enough to know whats what and how. I'm just wondering if it would be a waste of time and money to get a guidebook. The reason why I might get one is because I am bringing my autistic son for his second trip. Thanks in advance.
