After a lot of running about I finally obtained my Brazilian visa and continued along the Uruguayan coast to Punta del Este. It is very much like the worst of the Gold Coast (concrete sprawl and high-rises everywhere) but with even less charm and worse beaches. It didn´t help that the people at the hostel I stayed at sat on their laptops all day watching movies. During peak season the town fills up with rich Argentinians and Uruguayans but it was a ghost town during the days I was there.
I couldn't leave fast enough....
