I have been researching the city of Montevideo and these are the best links I could find:
From the New York Times travel section, 25 Hours in Montevideo (closer to 55 days for me). The sushi restaurant is on my street.
From Uruguayan horror/sci-fi director Fede Alvarez, Ataque de Pánico!. Studios compared this video to the South African YouTube clip-turned-blockbuster District 9, and Sr. Alvarez now has a multimillion dollar Hollywood contract.
ISCB's Conference Page where I did most of my research on hotels, buses, and weather. Plan Ceibal is at LATU (green marker on their map) but the upcoming ceibalJAM / eduJAM venue is closer to the westernmost markers, in Ciudad Vieja.
