Newbie here! Question about buying Hilton Free Night Certificates. I see people selling them with their "Diamond Account". How exactly does that work? I assumed the certificate itself would be sold and transferred?
Is there a wiki in that thread? (It can be found directly above the post on the page, there's a line "topic wiki" click the '+' to open it.)
If not, or if it's not complete enough, ask in that thread.
