Mid night taxi fare from yang shang Jin Yi hotel -haizhu square dade road to baiyun airport ?

Do you refer to Ying Shang Jin Yi Hotel(Dade Road Branch)?
If yes, generally speaking, it cost CNY 100 to 110 at the time.
You can consult the hotel about whether they provide pick-up service. The fare would be a little bit higher than the official taxi. Or just get a cab when you leaving the hotel. There will still have several cabs on the street at that time. Don't worry.
