Your destination in Guangzhou is Baiyun Airport or Guangzhou South Railway Station. I think you should all stay in Changlongsha Store, mainly for convenience. There is Airport Metro Line 3, South Station Metro Line 7, which goes directly to Hanxi Chimelong Station.
Go to the zoo for a day and watch the Chimelong Circus at night.

If you still have time in the evening, you can take Line 3 to Zhujiang Xincheng Station, flower city square and Haixinsha to enjoy the night view of the Pearl River.
On the fourth day, take Line 3 and transfer to Line 8 to the Cultural Park Station.
