Guangzhou to Hong Kong tickets

Hello!
If I book tickets online for a Guangzhou to Hong Kong ticket (4 adults for August 13), is is possible to have them delivered in a guest house in Chengdu? I don't know if it is a so-called and accepted hotel for that kind of business. I have no other option to catch my train after landing in Guangzhou on August 13...
Many thanks in advance.
