I had my honeymoon in January too couple of years ago
We spent one night in Balakot, then 2 nights in Shogran (during which we went bit up towards Siri. Though, it's quite difficult to reach there in this season. People were hiking. From there we left for Kashmir. Stayed in Muzaffarabad. Then couple of nights at Jogran Resort (kutton). Jogran is a must visit place if you are going Kashmir and in this season, the peace and serenity this place have, you won't find it anywhere else, I guess
During Kutton stay we had day trip to Shadra, Keran etc. From there we started our back journey. Had another night stay at Balakot and then left for KHI next morning. You can add Kel/ Arang Kel too if time/ budget allows. Our trip was arranged by a very good friend cum driver, who lives in Kiwai and it was amazing. It matters a lot who your driver is. I can say this because I have had solo trip after that and didn't enjoy it as much due to several planning hiccups.
