Need advise on duration on huangshan trip

Hi, I would like to know whether I can cover most of the attraction peaks for 2 days 1 night. My plan as follows:

1) reach there from shanghai at 10am.
2) using cable up and view some attraction
3) check in at Xihai Hotel and continue for some walk before watching sunset
4) next morning for sunset and continue some walk before check out
5) down to Tangkou and bus to Hangzhou or Shanghai

Thanaks in advance.
