Yar Ahmad,
One should plan things but not to this extent in this age 
Take corolla. City is fine too but corolla would be better. I have a feeling that you are a very good driver. The road is such that even average drivers make it to naran kaghaan.
You people are going to have fun yar. Just take a jeans, a couple of shirts and leave.
Sardi ho gi to kya ho ga? Yehi to adventure hy. Barish ho jaye gi to kya ho ga? You may have to stop somewhere. You will be with friends. You people can have fun anywhere.
Jidher dil kre ruk jana. Ja k dhund lena. Itni planning families ya mere jaise babe krte ache lgte hain.
It will be little crowded coz of summer vacations. In a way its good. If you want to avoid the rush, postpone till 25th of August. That's your call.
Have a safe and fun filled trip. If you want a driver, give me a call. I'm available free of cost
