You can get Starwood Preferred Guest Gold status for having just one stay at participating property in the Asia Pacific region. This offer is targeted to World MasterCard holders, but anyone can register using the link. This offer that has been going on for a while is expiring on March 31, 2013. You can access the Starwood’s web page for this offer here.
You need to sign up or register your existing account to this promotion using the link above. The terms and conditions state that you would need to settle your hotel folio using a World MasterCard, but I doubt that the actual credit card information, besides what type of card was used to settle the folio, is transferred to SPG.
