I purchased Accor Plus from the Indonesian website (using my real address and credit card from outside Indonesia). There's an option with two StayPlus nights for about $300 (US). I spent them on the Fairmont and Swissotel Singapore, where each night cost about $300, so I'm already well ahead without factoring in the discounts in room rates and dining, and the 20 status nights. There's also a bunch of coupons for breakfast and upgrades, but those are valid only in Indonesia.
