IHG Rewards Club: Double Points/Miles on all stays June 1 - July 31 (starting with your 2nd stay)

It's been awhile since a true systemwide bonus has come out IHG Rewards Club (nee Priority Club). In fact we haven't seen one yet in 2013. The first systemwide bonus of the year was only for new Priority Club members so that one didn't really count. Well now the wait is over the next offer is out. Here is the offer as it will appear on RC's Priority Club page tomorrow:

Earn Double Points or Double Miles on every qualifying stay, starting on your second stay at all IHG locations Worldwide. Stay at Staybridge Suites^® hotels or Candlewood Suites^® hotels and you’ll start earning double on your first qualifying stay. Full details,  registration and online booking Jun 1 - Jul 31, 13
