How easy is getting a taxi from Guangzhou station?

Hi, I will be arriving with my daughter (8) and cousin (15) and elderly mother in Guangzhou train station (from Hong Kong) in mid July. How easy is it to get a taxi at the station? In the past i have had difficulty getting a taxi from other places in Guangzhou as people just tended to step right in front of us and get into taxis. Will i be trying in vain to get one with four passengers plus luggage? Thanks!
