Some travelers recommend a diverse itinerary that includes Buenos Aires, Patagonia (El Calafate, El Chalten), Iguazu Falls, Mendoza, and Bariloche. Popular activities include hiking in Patagonia, visiting the Perito Moreno Glacier, and wine tasting in Mendoza.

According to forum posts, a typical three-week itinerary might include exploring Buenos Aires, flying to El Calafate for glacier tours, traveling to Bariloche for kayaking, and visiting Mendoza for its vineyards. Some also suggest including a visit to Iguazu Falls.

Travelers have called out the necessity of booking accommodations and domestic flights well in advance, especially during peak tourist seasons. Renting a car is recommended for flexibility in places like Patagonia, but travelers should be prepared for significant driving distances between destinations.

According to forum posts, Argentina offers reliable long-distance coach services that connect major cities like Buenos Aires, Mendoza, and Salta. Travelers have noted that these buses are comfortable, with options like full-reclining seats and included meals on overnight routes.

Some travelers said that local buses are available for shorter routes, such as from Rosario to Puerto Iguazú, stopping at various smaller towns along the way. Taxis are also a viable option for travel within cities or for covering distances such as a 300 km trip, though no specific cost details were provided.

Travelers have called out that train travel in Argentina is limited compared to other modes of transportation. The train network is not extensively developed, with few routes still operational for passenger service. However, destinations like Zárate or Mar del Plata can be reached by train from Buenos Aires, offering scenic views and local charm.

According to forum posts, travelers can exchange foreign currency such as USD, EUR, and GBP at airports, particularly at Banco de la Nación, as well as at various currency exchange offices (cambios) in major cities like Buenos Aires. The popular Florida Street in Buenos Aires is noted for its active currency exchange scene.

Many travelers recommend bringing USD in high denominations, especially $100 bills, for the best exchange rates. Euros and GBP are also acceptable but might fetch lower rates and are less commonly exchanged outside major tourist areas. It's important that all bills should be in good condition—crisp and unmarked.

Travelers have discussed multiple exchange rates, including the official bank rate, the Blue rate (unofficial market rate), and rates offered by Western Union and money exchange kiosks. The Blue rate generally offers more favorable exchange values. Some tourists use Western Union to transfer money to themselves for pickup in Argentina.

Posts indicate that using credit cards is increasingly viable due to rates close to the Blue market rate. However, ATMs are less preferred due to high fees and low withdrawal limits, and they dispense cash at the less favorable official rate.

According to forum posts, an American driver's license is generally accepted for renting a car in Argentina. However, while not mandatory, having an International Driving Permit (IDP) could be beneficial in case of police checks, especially if involved in an accident.

Travelers have mentioned that, at police checkpoints, besides a driver's license, you will likely need to present your passport and rental car documents. Keeping headlights on and seat belts fastened at all times is also advised to avoid unnecessary stops.

Some users have shared that tolls can be paid in cash. Regarding rental costs, one-way rentals can be significantly expensive, particularly for longer distances, with fees potentially reaching up to $1000. Additionally, crossing into neighboring countries like Chile might incur extra fees and require prior arrangement with the rental company.

Travelers have noted that driving less conspicuous cars like the Kangoo might reduce the likelihood of being stopped at checkpoints. When returning rental cars, it's advised to thoroughly document the vehicle's condition to avoid disputes over minor damages.

According to forum posts, many travelers believe that hiring a guide for visiting Iguazu Falls is not necessary. The trails are well-marked, and the park setups on both the Brazilian and Argentine sides facilitate independent touring. Travelers have emphasized that the area is easy to navigate on your own.

Travelers have called out that while visiting the Argentine side, spending a full day is essential as it offers more extensive trails and closer views of the falls, including the famous Garganta del Diablo. The Brazilian side, however, can be covered in about half a day and provides panoramic views of the falls.

Some visitors suggest avoiding the boat rides as they do not get very close to the Garganta del Diablo and are time-consuming. Instead, focusing on the walking trails on both sides of the falls is recommended for a comprehensive experience. For those short on time, managing both the Brazilian and Argentine sides in a single day is possible but requires an early start and efficient planning.

For an optimal visit, some users recommend arranging transportation such as taxis in advance, especially if planning to cover both sides in one day. This helps in avoiding delays and ensures a smoother transition between different parts of the park.

For domestic flights with Aerolineas Argentinas, the standard baggage allowance is 15 kg for checked luggage and 8 kg for hand luggage. Some travelers have shared that if your bag weighs between 15 and 23 kg, you will need to pay an additional fee, which is generally around ARS 850 at the airport.

If a bag exceeds the standard 15 kg limit but is under 23 kg, a fixed charge is applied. Several users noted the fixed excess baggage fee ranging from ARS 850 to ARS 3199 depending on when and where the excess weight fee is paid.

For international flights, Aerolineas Argentinas typically allows a baggage weight of 23 kg. This aligns with the international norms and provides a bit more leeway compared to their domestic flight rules.

Travelers have also discussed the complexity of adding extra baggage online. It appears that additional baggage can only be purchased as an extra bag, not by the kg. If you have purchased a fare that includes a baggage allowance, and your bag exceeds this allowance but is under 23 kg, the excess weight fee must be paid at the airport.

It has been mentioned that enforcement of these policies can sometimes vary, with some passengers not being charged for slightly overweight bags, although this is not guaranteed and seems to depend on the discretion of the check-in staff.

Many travelers have experienced difficulties in reaching Aerolineas Argentinas through their official channels, including the website, phone, and WhatsApp. Users have found some success by contacting specific representatives directly via email, such as a sales representative based in Miami. This method has reportedly resulted in prompt responses and solutions.

For issues like booking errors, changes in flight schedules, or obtaining refunds, forum members suggest persistently checking the airline's website for updates and using alternative booking platforms if direct booking fails. When seeking refunds, especially during disruptions like COVID-19, patience is necessary as processing can take several months. In some cases, direct contact with customer service representatives via email has led to faster resolution.

When needing to change or cancel flights, some travelers have had to visit airport counters directly, especially when other communication methods did not yield results. This approach has been necessary for urgent travel changes.

For those booking flights online, ensuring no spaces in personal details and using different browsers or devices can sometimes overcome technical issues on the Aerolineas Argentinas website.

According to forum posts, popular neighborhoods for staying in Buenos Aires include Palermo, Recoleta, and San Telmo. Palermo is favored for its trendy vibe and variety of restaurants, bars, and shops, while Recoleta is known for its beautiful architecture and upscale atmosphere. San Telmo is celebrated for its historical significance and vibrant cultural scene.

Travelers have called out Palermo and Recoleta as safe areas, particularly recommending Palermo Soho and Recoleta for their proximity to nightlife and dining options. These areas are also well-regarded for their accessibility to public transportation, making them convenient choices for tourists.

For those seeking an authentic local experience, San Telmo is often suggested. It's less touristy compared to other areas and offers a genuine feel of Buenos Aires' cultural heritage, especially during the antique fairs and tango performances.

Some travelers mentioned that staying in apartments or Airbnbs can be a good option for longer stays, particularly in Palermo and Recoleta, which provide a comfortable base for exploring the city.
