I grew up with the Birnbaum's book. My parents bought a new one each time we planned a trip and I just got the 2015 one to start looking at stuff for our 2017 trip. I'll buy the 17 one when it comes out, of course, but I figured it couldn't hurt to plan early, especially since my wife has never been before. That said, I find it easy to use, well organized and with just enough detail. It gives tips and suggestions of what rides to FP, what restaurants you absolutely must make reservations for, talks about different hotels, etc. There is a section for each park as well as all the many extras you can do. There is also a Birnbaum book designed for planning a trip with kids! (The main book does have kids stuff listed, but the kids one really caters toward them).
