By the Way, you should visit Patriata, Try both Chair Lifts (1-Pindi Point 2- Ayoubia) , Bhurban ( It's Cool and very silent place) , Nathia Gali, Ayoubia.
Try not to stay in Murree, as it's not the place what you imagine. Stay in Ayoubia is best choice. Rest is up to you, what you plan
Best of Luck
