Journey around South & Central America begins

Here's the plan for our next journey:

I travel first from Chile to Argentina with the group of 4 other persons: Pia, Laura, Petra (the sister of Laura) and Cristian.

We leave from Chile on 25th of November to Mendoza, Argentina

From Mendoza we are supposed to continue to Cordoba

From Cordoba to Buenos Aires on 30th

30th of November my friend Mikko arrives to Buenos Aires, where we are supposed to spend one week

After Buenos Aires we want to go to Iguazu Falls, but we don't yet know if we are going there via Argentina or Uruguay

12th of December my friend Petteri arrives to Foz do Iguazu and we are supposed to meet with him somewhere there

After Iguazu we travel with girls and boys to the direction of Rio De Janeiro (not sure yet if we're going to stop by at some places) and perhaps stopping in Sao Paolo to meet some more friends

Christmas we are supposed to spend on some island (e.g. Ilha Grande, which is quite close to Rio)

New Years we are going to spend in Rio de Janeiro and by then we are a group of 9-11 persons

After New Years me, Pia, Petteri, Nitta and her friend are taking a flight to Manaus, The Amazon where we are supposed to stay until the 12th of January

After Brazil we head to Columbia with Pia

From Columbia to Central America

And finally in Mexico in March

Mexico --> Finland
