I'm not going to lie; I've been using the Unofficial Guides since a former boyfriend introduced me to them two decades ago. If I'm going to a Disney park, I get the latest book so that I can read up on the tour plans, updates, etc., that I need to know to make the best use of my time.
This update did not disappoint. Along with updated information on the latest rides at Disneyland and Disney's California Adventure, I also got great information that will help me as a newly diagnosed Hashimoto's thyroiditis patient who has gone gluten-free.
This is not your typical guidebook, either. For those unfamiliar, Unofficial Guide writers pay full price to get into the parks, do not make their presence known, or in any way indicate that they are travel writers. They want to have the same experience as any other guest so that they can write frankly about their findings.
I can't recommend them highly enough.
