This pocket-sized guide was the only thing I needed to carry on my trip to Puerto Rico. With tips on the best beaches, wild life attraction, and restaurants, we were able to get the true authentic experience. Prices were exact and current, ratings and highlights were easy to find, and the cost was low. I would recommend this book for anyone who wants to get the most of their vacation without a big, heavy book.
