Hi Julian:
As a local from BA with 15 years experience receiving foreigners,
I will try to give you some help:
-- Try to buy in your travel agent a Visit Argentina pass. So you can fly
by cheap 4 or 5 times in Argentina. Ask also for the Mercosur pass:
it includes Uruguay, Paraguay and Brasil.
It's real that our buses are very comfortable, but I think you don't come
here to spend days in buses...
-- Walles season in Puerto Madryn begins in July. But it's not exact,
so you cannot be sure you can see them...
-- An option is to visit our Northwest: Salta province and the valleys around,
the path til Boliviam, are wonderfull to visit in winter.And you can reach
these points straight from Mendoza.
-- Uruguay: Their beaches are wonderful, but you come in our winter and
the city Montevideo it's nothing special. You should spend more time in Buenos Aires,
where you can find many interestings things to do/see even in winter season.
From BA you can cross in a 1 day tour to Colonia a nice colonial city.
-- Of course Iguazu falls is a Must place. Bus trip from BA is 19 hours.
But you can stop in San Ignacio, 4 hour before, to spend 3-4 hours visiting
the impresive jesuitic ruins. then any local bus will leave you in the falls.
There, try to choose a brasilian hotel, because they have better service than
our hotels. Tree days would be enough for the falls.
-- From Iguazu, there are very good buses to Porto Alegre (Brasil)
and from there to other places in Brasil, if you don't use air passes.
-- Brasil have many other very nice places and no so dangerous than Rio.
So you could consider to vist Rio for few days, and enjoy the other safer places.
Well, I hope this give you more ideas.
And if you need extra info about BA, or accommodation, emaill me
