Earn 500 Starpoints (probably valued at $10+) for just updating your stay preferences in your profile (literally takes 2 seconds) - just a matter of checking or unchecking a couple of boxes.
You need to register for the "More for You" promotion by 30 November and update your preferences by 15 December 2014.
Bonus points will be awarded 2-4 weeks after the promotion is over.
The More for You promotion also allows you to earn:
* Double Starpoints on stays of two or more eligible nights
* Triple Starpoints on eligible stays that include a Friday or Saturday night (Thursday or Friday night in the Middle East)
An eligible stay is one that includes two or more consecutive nights on an eligible rate that allows you to earn Starpoints. Stays need to be completed by 15 December 2014.
For those interested, SPG have also recently announced a partnership with Emirates where you can earn both Starpoints and Skywards Miles when you fly on Emirates or stay in a Starwood Hotel. There are also a number of reciprocal status benefits. More details here: http://www.emirates.com/english/skywards/about/partners/hoteā¦
