Query: Poor guidebook

While I applaud the authors for donating the profits from the book to children on Kauai, I'm sorry to say it is a very poor guidebook. I puchased this book and the Ultimate Kauai Guidebook, and the UKG is so much better. The Kauai Underground Guide is poorly organized and doesn't contain any "underground" informaiton. The UKG has MUCH more "underground" information and is much better organized with MUCH better maps. Furthermore, I want a guidebook that is opinionated. I want a guidebook to say things like "don't waste your time" or "this is definitely the best," and this book doesn't do that. When you read through the book, you get the annoying feeling of reading someone's travel memoirs. The authors get annoyingly "poetic" with their descriptions, and you almost feel like you're reading advertisements. I'm sorry to say, don't waste your money on this book, go for the Ultimate Kauai Guidebook -- it has everything you'll need.
