We primarily booked this hotel with the expectation that being located inside the national park that we would have some benefits like having extra time to access the falls. However, the all the trails are strictly blocked by National Park officers well ahead of published closing times.
We had a 2 night stay at Iguazu, as were arriving late in the afternoon, we chose to stay the first night at Ameria Portal, and the next night at Gran Melia.
Breakfast is served late at GM, and when we were ready to visit the falls, we were had no advantage and were in a battle with the hundreds of school children and other visitors.
As a number of trails had been closed as a result of damage from the 2022 floods, we completed all the trails within a 3 plus hours along with the multitudes of people on a hot day!
Although, we distintly remembered visiting all the trails (pre-floods) plus the Brazilian side on the same day the hotel staff discouraged us from going to the Brazilian side saying we would not have the time. On speaking with other visitors at the park we learned that the Brazilian side was in a much better condition and easily accessible!
Having finished all the trails on the Argentinian side before 2, we decided to return to our rooms and revisit around 4 when hopefully the majority of the crowds had left.
However, the trails were locked with chains.
If we return I would stay on the Brazilian side first and one night at another Iguazu hotel.
