SayedBhai, it will not be less than that ! 2ndly i would suggest spend sometime there at each spot, doing babusar pass and nori top in one day isn't good idea !
jeep fare are very high there, i took cj6 jeep from isb and visited, shugran, siri paye, naran, saifulmalook, lalazaar, nori top, lulu sar and babusar pass, all done and back to isb home with 5 person on board in 10k diesel 1 year back
