Go there! Do the tour. It is such a unique experience and one of the places in the world that makes you feel truly special for having been. I would love to return one day. Yes, so the journey to get there is long and bumpy but you will not regret it! Sure, it's expensive too but not compared to the truly unique experience that it is! The date of travel is not correct - went a few years ago but the tour experience has stayed with me and was one of the highlights in our South American tour!
