If you're spending three days at the Falls, you probably want to go to the Brazilian side too (nice walk, including the "mist", plus I liked the Bird Park near the park entrance for hundreds of free flying big tropical birds in a walk through aviary. I wasn't able to go, but I wish I had been able to see the big hydroelectric power plant near the three way border with Uruguay, which you apparently access from the Brazil side.
The bad news is that (for USA citizens) Brazil requires an advance visa, which is a $160 hassle plus visa service agency fees.
