We will be arriving in Iguazu from Salta after a 4 week trip. We have one week left before returning to Buenos Aires. We would appreciate any help in how to spend that time. We want to see the falls from both sides but after that we are not sure what to do. We had thought about Posadas and Ibera Wetlands. Is it feasible to do both. The lodges in Ibera are costly, so any ideas on a budget (US$75 - 100 for a double per night) places to stay would be helpful. Thanks to all who read and reply to the posts.
