Similar to the Marriott and Hilton statuses from 2 weeks ago, IHG offer Gold status after your next stay. The promotion appears specific to HP employees, though like most other 4 digit promotional codes with IHG it seems anyone can use it.

IHG gold doesn't get you very much when staying at their hotels — late check out, 10% bonus points plus a slightly better chance of an upgrade — but it's a useful thing to leverage status matching with competing chains!
