People wanting to visit Iguazu Falls can take an easy and fast flight to FOZ DO IGUACU, a brazilian city that has the best structure to host visitors. From there you can take the bus to the brazilian side one day and another bus to the argentinian side the other day. It is all very cheap, easy and fast. That thing about 16 or 20 hours to reach the falls is non-sense.

Iguazu Falls are not difficult to access. The 22 hours ride from Buenos Aires apply to buses, but you could easily fly from Buenos Aires to Puerto Iguazu in 90 minutes. The walkways in Argentina are not called "passeios inferiores". In Argentina you have the "upper trail" and "lower trail", as well as a train (Magic Kingdom like) that takes you near the Devil's Throat.
