Is it a good idea have three full days (four nights) for Jiuzhaigou Scenic Area with little kids (6 and 8)

I'm from Germany but live in Guangzhou.

We're three adults plan to walk around with the kids and have three full days in nature. We will stay in JZG Jiuxin Inn（Branch, 800 m from scenic park; the other two days are flight days. We will come on 1. of July and fly out on 5. of July.

Thanks for your opinion.
