Most of the "tips" in Mr. Greenberg's "book" can be obtained by talking to any frequent traveler yourself. Simply, the "book" does not deliver what it says it will. He talks more about the history of cruise ships than how to get a great deal on a cruise. He does not discuss how to get great service, he tells you how to make yourself a nusance with the people in the hospitality industry. Mr. Greenberg's negativity toward travel in general is also apparent. If you want to read a book on all the bad things about the travel industry, this book is for you. If you want to read a book about how to circumvent the ups and downs of the travel indsutry, you need to read another book.
