Say Hueque proved to be an excellent tour company to work with, and the experience they allowed me to have at Iguazu Falls (both Argentina and Brazil sides) was simply magnificent! They connected me with top-notch local tour guides (through Eco Iguazu) who were knowledgeable, friendly and efficient. Schedules were adhered to with care and individual arrangements (to/from hotels, to/from transportation hubs) were managed very skillfully. Prior to my trip, I had numerous email exchanges with representatives from Say Hueque - always helpful, responsive and so accommodating. They helped me step-by-step to craft a perfect itinerary that met my needs and interests. I would definitely work with Say Hueque again if considering a trip to South America.
