best way to get to Xinhui, Jiangmen from hongkong airport?

I am traveling with a 2 year old by myself with 3-4 bags of luggage. i like to get to Xinhui, Jiangmen as soon as i can, anyone know what time is the lastest ferry or bus will run? My other option is to stay in Hong Kong overnight then head to xinhui, jiangmen. if so, which hotel provide free transportation from airport to the hotel front door (will not be able to walk while carry all the luggage and a toddler). What will be the best way to get to xinhui (bus or ferry), again keeping in mind I will need help from one point to another.

Thank you in advance.
