Hello Lipp,
A confirmed client allowed us just to share permit but not guide, porter, transportation…, in this case, you need to pay full guide/porter/transportation. In this case, I suggest you take a guide cum porter (one man who carry your little luggage, speaks little English).
Kathmandu leaving on 23rd Feb, 26th-morning Entry at Jagat check post and 07th March exit from Dharapani and same day to Beshishahar the 08 March back to Kathmandu. So, Kathmandu to Kathmandu will be 14 days Manaslu Circuit Trek. Thus, your package cost will be the US $ 1215 with private transport round trip. If you wish public transport then $925
