Even though it might be arguably efficacious to see the falls in a hectic one-day (or even one-night) fling from BA, it might not be sagacious to do so. This destination is without question one of the most dramatic and memorable places we've visited. To give it short shrift is something to ponder carefully. We spent three days and two nights there and lusted for more time. To see the place fully, one should wander along the trails on the Argentine side, do the same on the Brazilian side, see it all from the air by copter, and then see it from the Zodiacs which take you right into the base of the falls (very, very wet, but absolutely wonderful). For a sense of the grandeur of this place, revisit the DVD of The Mission, for an overwrought Robert de Niro, a somewhat hysterical Jeremy Irons, and a hunky Liam Neeson (but I digress...). I would agree with Leslie that a few hours at Iguassu is not likely worth the trouble, stress and expense. I think that we all recognize that some things are not best visited on a cruise, much as we adore cruising. In my ever so humble opinion, Iguassu Falls is a destination which merits a couple of days. I certainly agree that adding a couple more days to the already fairly long PoP cruise will not be practical for most people - as it won't be for us; but fortunately, we've already been blessed with the waters of Iguassu Falls ruining my camera (when in a Zodiac under a falls, it is best to wrap the camera in a ziploc bag, which I did not happen to have on hand...) and do not have to fit that magnificent destination into the PoP pre-cruise or post-cruise.
