Hey Ali,
For the itinerary that I have below. Do you think 75K for 5 persons would be enough for hotels and food? 2 nights Naran, 3 nights Hunza and 3 nights Skardu.
DAY 1. Islamabad to Naran, night stay in Naran
Day 2. Leave for Hunza early morning visit rakaposhi view point on the way and then night stay in Hunza.
Day 3. Visit Baltit fort, Naltar Valley and Eagles Nest and Night stay in same hotel.
Day 4. Leave for Khunjrab early morning, visit attabad lake on the way, come back to Hunza Stay for the night. (I am thinking not to go Gilgit and stay in Hunza since it would already be a long journey to Khunjerab and back)
Day 5. leave for Skardu early morning. Will make it there by evening. Night stay in Skardu.
Day 6. Visit Shangrilla and Kachura lake as well as the cold desert then night stay in Skardu
