Transport from Huangshan Airport to hotel in Tangkou in the midnight

Hi, my flight will be arriving in the airport (understand that it is in Tunxi) at about 11.45 pm. Would like to ask, the only way to go to hotel in Tangkou area is cab? Is there any buses running from Tunxi airport to Tangkou at this hour?

If cab ride, roughly how much is the price? Is it easy to get a cab at 12 midnight and do they go by meter?

Thank you
