i picked this cruise because it's the most special. The other 2 are longer and cheaper, but I've been to the caribiean and to the mexican riviera, so these are all port that I haven't been. I will fly into Rio Brazil and than explore the city for a few day's than fly to the waterfalls. The biggest in the world! over 275 falls sorry I forgot the name, then fly to Buenos aires and go onboard.
