Seems that when you sign up for the offer it automatically registers you to the promo above as well that is 250 AIR MILES for 10 staying ten nights.
The offer code for this is 8733. Note that I am not suggesting that you should sign up for this.
The “Reel Summer” promo registration must use a recycled code or someone at the IHG has misprogrammed the offer. I truly doubt that you would earn AIR MILES (aren’t these something in Canada?).
