This book is based on the extensive cruising of the author as a guest of the cruise lines. It describes how he got started lecturing on cruise ships and describes the cruises that he and his wife have taken as a lecturer. It explains how anybody can apply to be a lecturer and describes the qualifications necessary for their acceptance. He compares the advantages and disadvantages of traveling as a lecturer on cruise ships. He points out that this is not for everybody, although it can be very enjoyable for a person who enjoys teaching and spending days on a ship at sea. It provides the amenities of living in a five-star resort and eating in five-star restaurants while traveling to far distant places and visiting foreign ports. It has the additional advantage of unpacking only once during the entire trip. Although continuous entertainment is provided onboard, perhaps the most enjoyable feature is the opportunity to meet and talk to many people from all over the world, thus broadening your outlook on life.
