Can anyone provide a comparison of the tour operators to DPRK? Koryo seems to have the most press but what about Juche or young pioneers? I understand that all the tours have basically the same itineraries and there isn't much difference in hotels so what drives difference in price? We have a group of four and are trying to decide whether to make ourselves a group or go on a group tour. This is one place it would seem the group travelers might be an interesting mix of people.
