No shots, no pills, no regrets. Bug bites did not seem to be a problem. The park closed at 5PM which was before dusk. I highly recommend staying at the Sheraton instead of the town.
I did not go to the Brazilian side since that would require another visa and possibly difficulties in the future when visiting other countries. Some countries want a yellow fever shot documentation if you've been to Brazil, and I refused to get the shot. Yellow fever and malaria are not in the Iguazu area, but the passport stamp and visa just say Brazil.
Since we're slightly off topic from the OP's original question, I will respond to the comments above for those contemplating a visit to Iguazu Falls either before or after their cruise.
We've never had a problem with the Brazilian visa in our passports. We have carried our yellow fever certificates with us, but we never have been asked for them. The full frontal view of the falls from the Brazilian side was unbelievably gorgeous - well worth the cost of the Brazilian visas.
We stayed in the town of Puerto Iguazu for 3 nights, rather than at the Sheraton - the savings made up for the cost of our Brazilian visas. Puerto Iguazu is closer to the Brazilian border, which was convenient for the day that we spent seeing the Brazilian side of the falls. We also enjoyed the experience of staying at a B&B in town and eating dinners at restaurants in town.
A Tour is not necessary for the Falls. Our B&B arranged for a driver for us for airport transfers and to both the Argentinian and Brazilian sides of the falls. (Most accommodations in Puerto Iguazu do likewise.) We did "stop" at the Sheraton on the two days that we visited the Argentinian side of the falls - one day for a drink and the air-conditioning to cool off - the other day for lunch.
If you only have one night at Iguazu Falls, stay at the Sheraton. But, if you stay for longer, consider staying at a B&B in town.
Also, if you are adding the Falls at either the beginning or end of your cruise, consider flying into or out of the Brazilian side of Iguazu Falls. (Only if you have the Brazilian visa.) Instead of connecting with an international flight in Buenos Aires, and traveling between the domestic and international airports (an hour apart), you can easily connect through Sao Paulo or Rio.
