Many thx sir 
The trip was one of lifetime best experiences.
There are 2 main problems if u r not staying in AJK or Valley Trekkers Lodges / Rest Houses.
1- Hotels: Very poor quality hotels throughout Neelum Valley and not suitable for families.
2- Food: Very limited choices and only local flavoured dishes which may not suit our taste.
Now if u are camping and cooking with family then no issues at all.
You can camp at any of the locations of AJK/Valley Trekkers Tourist Lodges or Rest Houses. They offered us free of charge camping if we wanted to camp in their premises.
Best camping locations are:
1- AJK Huts, Upper Neelum, Keran
2- AJK/Valley Trekkers Tourists Lodges in Keran
3- AJK Tourists Lodges in Sharda and Kel
4- Taobut Camping area near new fishing bridge under army supervision
Tents MUST be water proof and strong enough to hold heavy rains as u would be with family.
No security issues at all but take care of your things yourself as nobody would take responsibility of lost stuff.
