I was first introduced to the "Unofficial Guides" series back in 1994, and became an immediate convert. Each year's edition includes updates showing new rides/attractions, and includes data on weather, hotels, restaurants and even load times. The most useful feature? Clip-out "touring plans" that will allow you to make the most efficient use of your time, customized to various age levels and vacation durations. Highly recommended for long-time Disneyphiles and newbies alike.
