Hi, I would like to know where I can purchase (3 adults, 1 child) Round Trip tickets from Guangzhou East Railway Station to Beijing West, train T98B.(Departing 2 Apr, and coming back 7 Apr).How much are the tickets? I can't find any information on prices of Round Trip tickets. Also, I am currently working here, so I do not stay in a hotel. Can tickets be delivered to an address that isn't a hotel?

Thank you in advance.
Karen
