The city that you can explore each time you log in will be set accordingly to your Settings, you could change your Settings each time you are in a city for long periods of time but what if you’re just visiting for the day or weekend?
1) Explore your city
2) Change the visiting city
3) Select the Country and type the City name, it’s not case-sensitive but it is sensitive to incorrect spelling 😛 .
4) Check the “You are visiting” box; if you see a flag and your city name, then it means that you are visiting that city and all is well 🙂
