IHG is back with offering another Accelerate promotion, however, it seems to be highly targeted. I checked every one of my families accounts and none of us are eligible. If you are able to register, this promotion runs June 1, 2016 through August 31, 2016. This might only be for those in Europe and Asia, but I am not 100% sure yet.
Like most other IHG promotions, every eligible account has a unique promotion. You’ll need to register to see what your exact offer is. You’ll have to complete specific tasks to earn bonus points for every eligible stay (make sure to read the terms per task to ensure your rate qualifies).
