YMMV but it saved me close to half the BAR available through IHG and the other OTAs between special pricing and the code discount. Surprised me too as I would never have even thought to check an American Express Travel site thinking their prices would not be good. I think for IHG at least there is more of a chance of substantial discounts on North American properties from European sites because they are not subject to BRG due to use of a different currency. Now let's see how long it takes for the Vegas and Bangkok people to go to town on this.
