This is the same shit, you know, when I was here the last year, almost I had a heart attack probably I could have had a die, they are very thoughtless, the duration of excursion is 4 days, if you don´t a good health maybe you can die, i´m still young but my father... he suffer a lot, he took it badly, I was very sorry not to be able to help him, I only can say if you have some relatives with this kind of problems of health, don´t go.
