<p>One of our two college student daughters is going to do an internship this summer in Sao Paulo, Brazil; the other will be doing a study-abroad program in Buenos Aires, Argentina (we don’t have a lot of resources - they’re just good at raising money). My wife and I have mused about flying down there to visit them both, since this is an opportunity the likes of which are unlikely to occur again.</p>
<p>The two cities are a little over 1,000 miles apart. We could do a three-leg flight, but it would be really fascinating to get to see what’s between Sao Paulo and Buenos Aires at ground level. Is there reliable ground transportation for that long a trip, or would the highways be reasonable enough to make a one-way car rental a good option?</p>
<p>Gadad, I am so jealous! My daughter was in Argentina last fall and we went down to see her and we had a blast. We only stayed in Argentina but if I were you I would go over to the tripadviser site and click on South America and go to the forums (listed on the left). The people there will probably be able to help you. I would think you might like to go by bus. It is pretty inexpensive and you’ll get to see the area. They have these buses that the seats convert to beds and there is meal service complete with wine. My daughter took one of these and said it was great. I did a google search and did see that Lonely Planet suggests that it is cheaper to take a bus to the border and then take another rather than an international bus. That I really don’t know. One thing to be aware of is that you will need a visa to go into Brazil. It is about $100. </p>
<p>If you have any questions about Argentina, I may be able to help you. You and your daughters are sooooo lucky!</p>
<p>When I was in Buenos Aires I was going to try to stop at Iguazu falls and then Rio on the way back to the USA. However, the airlines went on strike, as they do very frequently apparently, so I wasn’t able to do it.</p>
<p>Sorry, I don’t have any useful info for you other than recommending Iguazu falls even though I’ve unfortunately never been there.</p>
<p>I did, however, do a jungle trip to Angel Falls and Canaima in Venezuela once. That was a very interesting trip. If you can swing visiting your kids as an excuse to see some of SA, it’s worth it.</p>
