butt sab CNG will be last at Manshera......... not after that. and u shud use petrol anywayzzz.
5 dayz are less for this trip. if u have to travel by road ul take 3-4 dayz on road only coz u r with family....... u shud increase ur time frame.
from lahore to jang-bahtar interchage ul need atleast 5.5 hours. then ul enter KKH hassanabdal to Raikot bridge is atleast 15 hours on ur car also add a few more houre coz u have small car no a jeep etc........
personally i think u will reach raikot bridge from hassanabadal in 20hrs......
from raikot bridge to fairy meadows and bak u already know from many threads so u can c that u have not enuf time.
i have travelled many times on KKH and a couple of times on my Mehran and 1 on Cultus. so i like to think my guess is accurate.
with fam u r better off going to naran on coure and then take jeep from there till raikot bridge via babusar pass. this will be more realistic for u......
