One of our favorite budget travel tricks is to book flights with long (~24 hour) layovers in a new city. I mean, it’s essentially a free flight, so how can we say no? Whether you’re on a crazy 5-countries-in-5-days backpacking trip or a long layover in a new city (we’re quite familiar with both), our 24 hour guides are perfect for getting a taste of a new city and checking out some of the highlights.
