We're taking a trip in mid-November, cashing in some frequent flier miles. We would like to spend about 4 nights in BA, 2 nights in Iguassu Falls at the Sheraton, then 3 nights in Rio, but wondering if we would like to spend one more night at Iguassu and one less in Rio. Any thoughts on an itinerary? Any idea what air fare is going to be BA to Iguassu and Iguassu to Rio? It would be nice to get a hotel and air fare package with the Sheraton, but I haven't seen any, only packages with organized tours, which we don't want to do.
