Fodor's Puerto Rico (Full-color Travel Guide)
I found this book to have answers to all my questions about lodging, tourist spots, leisure activities, food, parks and natural places, entertainment, festivals, etc. It had suggestions for family vacations, eco-tourism, gay interests, romantic settings and just about any other type of vacation for which you could wish. It marks restaurants (and a few other things) with dollar signs (one, two, or three) to rate their cost. The book discusses different aspects of travel, divided by region, and it includes a tear-out road map at the back of the book (opens to about 18 x 24"). The book is small enough to fit into a handbag or tote, though it might feel heavy by the end of the day.
