Fodor's Expert Review Sheraton International Iguazú

That thundering you hear in the distance lets you know how close this hotel is to the falls—the lobby opens right onto the park trails, and half the rooms have big balconies with fabulous falls views. (Be sure to reserve one of these well in advance, as they're the most popular). The rooms are perfectly serviceable, with sleek furnishings and wall-to-wall windows. The spa has a gorgeous hot tub and treatment tents on an outdoor deck. You can see the rising mist over the falls from the beautiful swimming pool, which is surrounded by palm trees and jungle.
