How much it costs from Beijing airport to Tianjin port?

Hi,
My wife and I are joining a cruise starting from Tianjin port. We arrive Beijing one day earlier. We would like to take a taxi direct from the Beijing airport to a Tianjing Hotel which is reasonably near our embarking to the cruise so that we don't have to rush the next day. Can you kindly let us know how much does it cost and any better suggestion for me? Which hotel is Tianjin is good? Thank you very much.
