Practical tips
Coaches and flights, especially on popular routes like Buenos Aires to Posadas, can fill up quickly during peak travel periods and long weekends. Secure your tickets in advance to avoid disappointment.
Argentine long-distance coaches offer 'semi-cama' (reclining seats) and 'cama' (fully reclining beds). 'Cama' seats are more expensive but offer superior comfort for overnight journeys, making them a worthwhile upgrade.
Always confirm the exact terminal or port for your departure. In major cities, there might be multiple bus terminals or airports. Double-checking prevents last-minute stress and ensures you don't miss your connection.
When comparing flight vs. bus, remember to add the time and cost to reach the airport from the city center. Bus terminals are often more centrally located and easier to access by public transport.
For overnight bus trips, bring a neck pillow, blanket, snacks, water, and entertainment. Some buses offer meals, but it's always good to be prepared, especially for longer routes.
