Brother,
Thanks for replying and am feeling comfortable that you have already spend time on these dates.
Will all the murree & connecting roads will be blocked or just Mall road?
I don't prefer to stay on Mall Road. I always find some resort type place around Bagh e Shaheedan (Kashmir Point) for better commute instead of getting stuck at GPO.
Your given plan seems reasonable to exit before 10am and entry after 7pm but I will be reaching murree at around 7-8am morning so I planned to leave Murree after some rest & Jumma Prayer i.e. 2-3pm.
Now this all depends upon roads, if I would be able to move from Kashmir point to Jheeka Gali and then to anywhere bhurban, neelum or patriata.
