Jiuzhaigou, HUANGLONG

We plan to tour JZG and HL from Chengdu on 29/7 to JZG by bus with 2 nights in JZG. Visit JZG scenic area the next day and travel to Chuanzhusi on 31/7 morning then take bus to Huanglong scenic area. After visiting HL travel back to Chuanzhusi for a night stay before going back to CD the next morning.
Is the above workable? Any hotel in Chuanzhusi and is it easy to get buses for the above plan?

Thank you
