Quick answer
Stay inside the airport for short layovers. Leave only when you have a long buffer, correct entry documents, luggage handled and a simple route back to the terminal.
- Check visa and entry rules before assuming you can exit.
- Count immigration, security and walking time.
- Keep boarding time, not departure time, as your deadline.
- Choose one nearby plan, not a city-wide itinerary.
- Save return train or bus options before leaving.
