Is the Sheraton worth staying at? I read that it is the only hotel actually located IN the Iguazu National Park. I will be arriving in the late afternoon from the Brazil side and will only be staying 1 full day until we leave from the airport for Buenos Aires at 6pm. Most of the comments focus on it's great location, Is it better to stay there or stay in town and grab a cab in the morning? People mentioned that if you are already inside the park you can start earlier than those coming from outside the park.
