[EX Q]: This book was brand new when I received it. However, it did not arrive for 20 days after I ordered it.
[EX A]: Negative

[EX Q]: What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.
[EX A]: Positive

[EX Q]: Got this at a great deal and loved the movie. It's nice that I can watch it on my iTouch anytime and not on Flixster under restrictions.
[EX A]:
Positive
