I'm going to Buenos Aires tonight through Sunday night *knock on wood* with three friends. It is my second time and their first time; what day trips can we do on either Saturday or Sunday? I was thinking of taking the boat to Colonia but we could also nonrev over to MVD
(which doesn't sound as interesting as Colonia frankly). We're also open to any daytrips near B.A., preferably not to any country that doesn't require a visa. Any suggestions?
