Hi, I was wondering if anyone could give me some advice?

My girlfriend and I are planning to go to Huangshan on the first weekend in December, flying in from Shanghai on the Sat and flying out on Mon evening. Hopefully, we'll get into Huangshan city before 5pm - are there any buses out to the scenic area at this time or after? Also, is it possible to get onto the mountain in the evening (to get to our hotel)?

We're hoping to do the mountain on the Sunday and Hongtsun village on the Monday.

Thanks.
