Hello, I am arriving Guangzhou Baiyun Airport 12.20pm, how can I get to Zhuhai Gongbei?

Is there a train or coach direct to Zhuhai Gongbei and how long does it take?

If I stay in Hotel Canton, on my day of return, I need to check in Airport by 11.00am , is there a train or coach direct to Baiyun Airport, how long does it take?

Thank you.
