guangzhou airport shuttle #5

4 of us will be arriving at Baiyun airport at 21:30 on a Thursday night. It was suggested we catch airport shuttle number 5 to Suijing Building, then catch a cab to the Hilton Baiyun. Because this will be late at night, what is the area around the Suijing Building safe at night, and how easy is it to catch a yellow or blue cab from there?
