1. Look at the website for lan.com. The rt cost should be 180 dollars if you book ahead. Do not use Argentine airlines,because your flight could be cancelled even if they are not on strike.
2. The cost for the remise from the airport to the park is 35 pesos.
3. The park costs 30 pesos per day;if you buy your next day together then the 2nd day is 15 pesos.
4. Two days are perfect for the falls, you will be able to see everything.The falls ae spectacular. Se the movie the Mission with Robert DeNiro. It was filmed at the FAlls.
5. The Sheraton is undergoing a remodel right now and will be finished by June. They will have new lobby,restaurants,spa, and new pools. It is the only hotel within the park and located right on the trails to the falls.
The other hotel mentioned in previous post is very nice, but requires taxi or bus to the falls each day. The Sheraton rooms looking directly at the falls are more than the rooms overlooking the jungle. Prices vary according to season.
6. There are two day trips to the falls, but check prices between the tours and self directed tour. The tours vary in price depending if you take the bus(18hrs or fly 1-1/2hrs). You do not need a tour guide, the walks through the park can be done independently. Also, tours are available within the park. For example,the Grand Adventure(105 pesos) includes 2 boat trips and a jeep ride through the jungle. The train ride is included in the admission price of the park.
To go to the Brazil side, you officially need a visa, but it's possible to go without a visa from the remise drivers in the Sheraton and other places in town.
Hope that this is helpful.
Cheers!!
