First of all many congrats on your marriage, supposing you just got married and its not one of those cases where you finally spared time for honey moon after being together for ages 
Secondly, honeymoon is something which gives you a little privacy from your relatives where you can spare time for each other and make every moment a memorable one. Like they say .... Love is: Stealing a moment when you have eternity together.
Now lets talk about you plan ..... Discuss with your wife what she wants to do, are you two going to visit places or the plan is to stay somewhere clam and quite, enjoy every pulse of beautiful weather with a little touch of sight seeing and shooting some snaps for your nice photo album.
I maybe wrong but for honeymoon one place is more than enough provided that you choose the right place at first time.
Muree is nice to look around but I would suggest getting a hotel in Nathia gali. You can enjoy chair lifts and cabin cars, lunch in PatriyataDepending on your budget and time frame, you can head for Kaghan valley as well. Lalazar is a beautiful place but the track is closed mostly due to rainy season. Jheel Saif ul Malook is over crowded and lost its elegance (in my opinion). Lulusar lake seems more beautiful than that. Shogran is a nice place but you wont find anything else around. Steep road from Kiwai to Shogran is also not in good condition and after reaching Shogran one would think ""is that it?"" after the trip hassle. Possibility of visiting Siri Paye depends on weather condition. Jeeps will just skid here and there and your wife wont be enjoying that a lot.
Sorry if I was not of any help but I have been to all these places many times and I know the difference between seeing pictures of some places and actually being there. I mentioned all this because after all its a honeymoon package and one does not wish to ruin it due to poor planning.
