If you're with family, I would recommend you to make your plan easier.
Day 1: Lahore to Rawalpindi - Stay in Rawalpindi/Islamabad
Day 2: Rawalpindi to Muzaffarabad - Stay in Muzaffarabad (Sangam hotel has good river view)
Day 3: Muzaffarabad to Kutton (Jagran Resort, You should confirm the booking from Muzaffarabad)
Day 4: Kutton to Rawalpindi
Day 5: Rawalpindi to Lahore
There are some good hotels in Keran and Sharda but nothing as good as Kutton's rest house. It would be great if you can take a small stove and packed food with you.
