Priority club is rolling out a new promotion where you can earn double points or double miles on qualifying stays starting on your second stay.  Definitely a good promotion if you are going to stay at a Priority Club hotel anyway, but not better than the 3 stays for a free night promotion at Starwood.

You can register for the promotion through this link.
