I LOVE this guide. It is small and compact so you can carry it around the park. It makes MK seem like both a Disney vacation and a sightseeing trip! The tidbits about the Imagineering process are "funducational." It's like Pal Mickey on Barry Bonds-level steroids! And much cheaper! Indispensable - especially if you love Disney the organization as well as the Disney the theme park.
I highly recommend this, it's chock full of fun and random facts about the attractions and the history behind each attraction as well as gives a small glimpse f the imagineering process. Super cool, definitely a good read!!!
