Subject: Last minute Buenos Aires help

An opportunity just presented itself to travel to Buenos Aires, in exactly one month. I have the flexibility of making it a trip of from one to two weeks. Only one or two days will be for business. I have never been.

Since I need to book my tickets as soon as possible, I'd like to ask for the barest bit of guidance on how much time I should allow for B.A. and the environs. And what if I make the trip to the Iguazu Falls-- how much time should I allot? Are there any other must-sees that are off my radar, that I need to plan time for?

I need good food, museums, markets, and natural beauty. I do not need a beach.

With thanks for everything I've gotten from this list, Joel, in a Chicago buried under a foot of snow
