I received a targeted promotion by Wyndham by email where you can earn 16,000 points for one stay at one of their 20 new properties up to 3 stays which = 48,000 points. The promotion runs from Aug 6-Oct 6. According to the T&C, you must be an active member, must have received and clicked the email, and must stay by Oct 9, 2012. Loyalty Traveler details out the properties and T&C. So apparently, you may be able to book a "phantom stay" and get points if your credit card is charged. If you find a cheap hotel rate and book 3 times, that is a whole lot of points which could be used to book hotel stays you really want or transfer to your choice of airlines listed here.
Summer is 4x Sweeter" promotion where you can earn 4 times the points or miles after your second stay. You just need to register and stay by Sept 13, 2012...which is coming up fast! I'll actually be staying at the Wyndham Royal Gardens at Waikiki soon! However, it will only be one stay.
I am not sure if these promotions can be combined but I'd say that these are some pretty sweet promos!
Just got an eh promotion where you can get 2,000 points for trying greatfunonline.com for $1 for the first month. You can cancel afterwards and still get to keep the points. Just don't forget to cancel :p
