Doesn't the price have to do too with how much the guide has to pay for that person, all the fees, etc. How many people are coming, etc? That could be why it costs so much. Pay for the air fair, lodging, food, etc for the teacher (famous) and divide that by how many people are coming, etc. I think that is how they do it. Maybe the price isn't so high. IF I wanted to see them I would go for that price.
