Travel books can give you information you didn't even know you needed until you read it. Transportation tips can be extremely helpful when you're in a new city and are unfamiliar with the public transit system. And when you have no idea how you should plan your week away, there are books about travel that also provide suggested itineraries. You can also get etiquette tips to help you interact with locals, as well as safety advice to ensure your trip is as fun and frictionless as possible.
Whether you're visiting Europe or Latin America, travel books are a great resource to help you make the most of your trip.
