@ Unware:
Thanks a lot for your input, brother. We plan to visit places, however don't want to over travel or something, we have 5-6 days in hand, starting from Abbottabad and would like to utilize it the way the we visit some of the best possible places without being traveling all the time.
So in short we could just visit Murree, Abbottabad, Nathiagali & Shogran, if that could be covered in these 5-6 days. Our objective, as many other honeymoon couples, is to spend quality time with each other, instead of rushing to cover all the places 
I will definitely contact the above mentioned people for their input too.
