Brazil - Luggage Storage at IGU?

We will be landing at IGU early in the morning and are thinking about going straight to the Brazilian side of Iguacu Falls from the airport. What is our best option in terms of storing luggage? Would you consider the storage at the airport secure to leave our stuff and then return later that day to pick it up?

Any other ideas on the best way to do this? Our hotel is on the Argentine side.

Thanks

All airports and bus terminals in Brazil have luggage storage. I have found them safe, but of course, all zippered compartments have my own locks on them.
There are also luggage lockers at the park entrance. If you are going on from there to Argentina, using them would save backtracking to the airport.

Good to know, sounds like that would be an easier method. I assume that they're big enough to handle almost any size bags.

Thanks
