Delivery train ticket to hotel in Beijing

Hello!

Our time in Beijing is short, so we would prefer to buy our tickets online, and have them delivered to our hotel (we are fine with the small fee). If that's the case, we do not need to be present to have our passports checked agains the tickets, right? The concierge should be able to sign for our tickets on our behalf?

At this point, it looks like the tickets may be delivered to our hotel before our arrival. I trust that it's not a big issue?
