As announced by the Starwood lurker over on flyertalk, if you register at spgpromos.com/insider you can earn a bonus 2015 spg points on your next stay before the end of the year! It'll need to be a qualifying stay (so not an award booking, not one booked with an OTA etc), but it doesn't matter if it's a pre-existing booking or not. You just need to have registered at spgpromos.com/insider before you checkin. From the look of it, checkin needs to be after 30th November, and checkout on or before 31st December. Only a one-time bonus, but a nice bonus none the less! Could almost be worth a cheap mattress run for, especially if you're very close to requalifying / hitting the next level. BRGs with Starwood (Best Rate Guarantee) get you either 20% off or 2000 spg points, so a cheap stay with a successful BRG claim and this offer could net you a nice slug of points. Probably much easier in the states or asia though, as the UK Starwood properties tend to be a little more expensive, but worth a quick look if you'll be near something suitable.
