Taxi from Nanning Airport to downtown late at night.

Hello, How late at night can I get a taxi from the airport to a hotel in the city. Late flight is coming in at about 1:30 in the morning? Do you think there will be a problem if I don't speak too much Chinese? Do I have to negotiate the price of the taxi? Thank You for your help. Or is there another way to get to NN? xiexie
