What is the cost? How difficult is the hiking?
Slightly amended the itinerary, to fit even more into less time, and finalised the dates. I'll have the cost in the next day or so - suffice to say, the more people we have, the cheaper it will be.
The hiking will be easy - unlike in the Himalayas or in the high Andes or Rockies, this area is at low altitude, and there will be porters carrying everything (unlike most commercial treks in the area).
