Hangzhou West Bus Station to Huangshan

I am planning on taking the early morning bus on 27 December2015 but I cannot decide to either alight at Tangkou or Tunxi. I am thinking of spending two nights in total at this area before heading on to Shanghai.

Is it possible for me to get a cable car straight up the mountain upon alighting from the bus, spend one night up the mountain, descent and stay in either Tango or Tunxi? Also, I read that several cable cars will not be operating but I cannot for the life of me find any websites which provides me with the information on the date I will be going. If I plan to go up the mountain straight, I will need to store my luggages somewhere for the night, yes?

Lastly, Tangkou or Tunxi for the second night? Haha. Thanks in advance!
