Can't help with the Iguazu question (but it does seem a hell of a long way in one day!)

You can fly to Iguazu from BA with either Aerolineas Argentinas or Lan, and there are several flights a day but you're still really pushing it for a day trip - it takes several hours to see even one side of the falls, let alone both. I'd really consider staying overnight to get the most out of it: if you're coughing up for the airfare anyway, it's a shame to rush things?

Take an early morning flight in (sit on the right side to see the falls - awesome!) and the late flight out to see it in one day. The Sheraton is quite expensive and we felt the food was pretty dismal/overpriced (they have a captive audience). ie:; Caesar Salad had some kind of mayonnaise dressing. If you do stay overnight, include a side trip to Caves of Wanda nearby. Really interesting and purchase some lovely stones. Otherwise we felt 2 whole days was a lot. We only went to the Argentinian side, did not want to pay for the Brazilian Visa for a brief visit.

This is hardly a day trip from Buenos Aires. Try to stay over night .Good luck

Thanks a lot for your resposes.. This definately helps!
