Good Basic Guide to Cruising . I bought the book to begin CLIA training.  This book is very basic, but covers many different aspects of the cruise industry.  If you are beginning to work in cruise sales, or are just interested in cruising, I would definitely recommend it.
POS

Great book for 25 years ago, not current! . Please! A great idea 25 years ago, but I think the best in-shape player is Mr. Woods, period. This book was like Jack Lalane meets golf, lot's of enthusiasm but not current training
NEG

Read Clayton Christensen's Books Instead . This book covers much of the same ground that Clayton Christensen explored in his three revolutionary books: The Innovator's Dilemma, The Innovator's Solution, and Seeing What's Next. Truthfully, those books do a far superior job of explaining the dynamics of innovation in comparison to the performance of this book. Utterback does have very insightful comments on the standardization of product design, but outside of that section, the book is not particularly exemplary. For those interested in mastering the art of innovation, the game begins and ends with Clayton Christensen
