This book was recommended to me by a friend who lives in Oahu, who said it was one of the most accurate guidebooks about the island. The writers don't announce themselves to the hotels/restaurants and subsequently receive the same service you or I would receive - their descriptions of hotels, restaurants, shopping, tourist attractions and beaches were accurate and invaluable. We never even bought a street map as the maps in the books were good enough - we only got lost once!! In addition, although guidebooks by their nature go out of date very quickly, if you buy the book you will get access to the password for the writers' website, and any changes to the book are posted there. I'd definitely recommend this book if you're going to Oahu.
