murree is a big no no, If money isnt a problem, then a trip to PC-muzzaferabad, Nathiagali and bhurban sounds alot better, If you manage a private rent a car with a driver and you deal with them for the all places that would be even great,
Abotabad, Murree (just a day trip), Patriata, PC-Bhurban, Nathiagali, Muzzaferabad, these places sound much better, Murree is a big big mess now with all the kachra/crap over their, too much vulgarity,
Altho if you could manage to get a hold of the tehmina duldana resort/huts, they are a bit away from Murree but i guess its walking distance, should be good for a honeymoon couple.
