If you go out by yourself in a strange city, you might get lost. What should you do? How can you find your way? Of course, if you never go out alone, you won't get lost, but you will also miss a lot of good experiences.
One thing you can do in case you get lost is take a map along. It might also be a good idea to take a card from your hotel, so you have the hotel's address. If the map doesn's help you, or if you forget to take one, you must ask how to get where you're going. You can ask, for example, "There is NovaHotel? 'or " How do I get to Nova Hotel?"or "Do you know where Nova Hotelis?" Police officers and clerks in shops are often helpful when you ask directions.
