I studied abroad this past summer; I went to Brazil with a new program that St. Mary's University (San Antonio, TX) offered. It was an intensive (emphasis on intensive) Southern Cone Studies Certificate Program. We received a total of 15hrs for just the summer. And I went to Rio de Janeiro for a weekend...IT WAS GRRRRREAT!!!!! I actually hope to go back in a couple of years at least just to visit, God willing. And yeah it was expensive (between $9,000-$10,000) but all in all it was worth it especially for the number of hours we got.
Good Luck and just do it!
