Puerto Iguazu, Argentina
Not worth paying for this tour if you're staying at the Sheraton in the park. What the tour provides is all free if you're staying in the park. WE asked for a refund, and after wasting a whole day on the phone talking to the various travel agencies, nothing came about. Lesson learnt!
El Calafate, Argentina
Absolutely FANTASTIC. The bus was about 1.5 hours late, however being in SA, not worried as times are not as strictly followed as US. Very professional and thorough. We would recommend this tour anytime. We also added the 1/2 day walk on the glacier to this at the last minute. Well worth it!
