Taxi fee from Huangshan North to Tangkou town

Hello,
We are a group of 4 people travelling from Shanghai to Huangshan in middle May, is it the busy time as in expect high volume of people? We are likely to travel on G1509 arriving at 13.13 at Huangshan North station. We need to drop off luggage so want to know which town is better Tunxi (is it far from Huangshan North?) or Tangkou? As we will stay at the mountain on the same day if its doable and stay another night where our luggage are stored at. How much is the taxi to each town? as its easier to share with 4 people.
