I agree with the previous reviewer. There is a lot of inaccurate information (phone numbers, prices) and there is much that is not included, as compared with other guides. It does seem that the author has "heard" about, rather than experienced first hand, some of the things he includes. For the independent, budget traveller, I would not recommend this book. I just returned from Puerto Rico and used Lonely planet and Let's go PR. Let's go was the best one of the bunch! LP was next best. If you have to choose one, Let's Go would be it. On the other hand, if $$ is not the primary concern, Explore Puerto Rico does include more complete and interesting historical review and details of the environment and makes for a good read for a day at the beach.
