I did send them a reply to the e-mail (with my pdf-print of the alternative page). No answer... I mean, I understand that IHG is pulling up some creapy arguments (like 2nd person surcharge for a double room) in order to not honor a lower rate found on a different page, since they would have to give you the room for free according to their BRG, but accor? Come on... 10% below the other price found - that is definitively less than the 25% or so they have to pay to orbitz/expedia/... for selling their hotel rooms.
