The respected Frommer really falls to the bottom of the pile after this book. We took our first visit to Puerto Rico last month and we looking for what the reviews promised. Well, unless you want information about San Juan and Old San Juan, forget about it. There was NO info about our resort - The Copamarina - which, we've learned is in another of Frommer's books as a recommended spot. We were staying in the southern portion of the island and there's little info in the book for that area. We were particularly interested in purchasing the masks worn at Carnivale...the shops recommended in the book no longer exist. The Fox-Delicias Mall in Ponce is completely closed and empty for renovation.
