The New York Times has paired with Taschen to create 36 Hours: 125 Weekends in Europe. The book is basically an encyclopedia full of getaways and weekend trips in Europe. The book uses beautiful imagery and detailed schedules to help you plan the best possible time in Europe.
The book is color-coded and organized into five different regions for easy navigation. An index at the back makes it easy to look up specific places on your trip as well. Each entry starts with an overview and then breaks down a 36 hour plan of action. Some of the larger cities have multiple 36 hour action plans that are geared towards different types of people.
A travel guide that doubles as a coffee table book, 36 Hours: 125 Weekends in Europe is definitely worth a read.
