I am a huge fan of lonely planet. But this book is really disappointing. It lacks the depth and research of some of the others. The chapters lack the depth and those little nuggets around the areas. Not enough about things to do, places to stay. It should stick to more exotic regions. May be they didn't employ the tourists to write this book - probably they needed people from the exotic locations such as Africa, China, India or South America to write this book.
Or it could be because UK is too big to be covered by one single edition. I doubt the second reason though
