Rio and Foz do Iguacu

Hello - I'm actually going to stay at that same hotel by the falls. If you don't mind sharing, how far did you walk into the park to get those shots when the park was closed to the public? Any information of better places to go to would be greatly appreciated. I only have 2 days there and would like to get out for sunrise / sunset as much as I can and I wont have time to scope out the area before the first morning sunrise timing. thank you!
