The Unofficial Guide truly made our last trip Amazing. I can't say enough great things about their well researched touring plans and how effective they really are.
I also like to use their website as a companion to the book. They will post book updates, updated touring plans with the new rides, and recent WDW news so you feel like you are constantly getting the most up to date version the whole yearl
For someone who really likes to do the research and planning, the Unofficial Guide is the only choice for me.
