There will be no any problem for you just get out of your city is difficult only.
It will tmake 3 to 4 hours from Islamabad to Muzafarabaf, similarly it will take further 3 to 4 hours till Kundal Shahi - Kutton first night stay suggested here. Next day travel forward tonwards karen, sharda and go tillto Kel, your 2nd night stay. Next day go to Tavobat and return back to Mel.
Normal hotels are available in kutton and Mel. Road conditions are good maximum. You better estimate fuel consumption of your carcity.
