Couples, if your relationship cannot handle this type of pressure, take a train or bus. T here are things you can do to get un-lost. If in a small town, try going in one direction or downhill. Eventually you will come to the city wall or a dead-end. If at the wall, go one direction until you come to a gate.
Gates are always on maps.
If instead you come to a dead end, go back to where you started and try to retrace your steps. For example, my wife and I found ourselves in a small piazza with a church in a quadrant of Siena. Even now with maps, I have never unambiguously identified it. We vainly tried to retrace our steps, and by chance at one point we saw the city wall. By the time we got to the wall, we saw the Roman Gate.
