Trzinko, I liked your 'Don't ask me which side is better, probably the one you see first!" I agree with how you responded because both sides are truly spectacular. I was there sometime before 2010. ...liked the experience very much, but if I were to do it again, I'd rather be traveling with a partner or two. I did not like this particular trip or place as a solo traveler, but I loved the falls and the hotel in which I stayed. The hotel was on the Brasiian side right in the park itself. ...outstanding natural beautry reign supreme! Was asked by my guide who had been hired via my late carioca travel agent if I'd wanted to go to a sauna; I declined the offer because I'd wanted to enjoy "the boys" in Rio which was my next stop on this trip. ...had a Brasil pass during this particular trip, so I was able to experience a lot of Brasil.
Keep on enjoying and experiencing and updating us when you get the opportunity!!!
