HongKong Airport-Guangzhou by bus, going to Aloft GZ Tianhe

Hi,
We are group of 3 adults, with 4 bags.
Planning to take HKAirport bus to GZ on 12th April 2018.
Scheduled to arrive in HKAirport at 1900hrs
I notice there are few stops in GZ city to choose from.
Can someone recommend which bus stop in GZ City to stop at? Our destination is Aloft Tianhe hotel.
I understand that we have to take Taxi to go to the hotel

Thanks for the info
