"WPP Group's Hyatt code (10167) is for the world's largest advertising holding company (parent of Ogilvy, JWT, Grey, etc.). WPP has a major London/NYC presence. Hyatt's enforcement pattern: Park Hyatt and Andaz properties in London and NYC carry higher verification risk for corporate codes. FlyerTalk's Hyatt thread documented 50% check rate at Park Hyatt across multiple countries. WPP's diverse subsidiary structure means hotel staff may have difficulty confirming WPP employee status vs. a subsidiary employee."

"I can inform you that if someone checks into the Park Hyatt Sydney on a discounted corporate code, and I try to book a revenue stay, my rate will be higher than had they not used the code in order to stabilise the average room rate. This will occur at all Hyatt properties that operate with a floating rate of the day based on availability. So it does indeed affect you."

"I agree with that, but I do think that Hyatt would garner a solid amount of business by offering a FT discount code. If Hyatt did this they would get some very good press here on FT and to my knowledge be the first large hotel/airline to offer such a discount to us. If the discount was decent enough...something greater than AAA discount, they would probably steal some biz from the competition. I belong to other forums where corporations do offer forum members a unique discount. Of course in the matter of minutes that code would be plastered all over fatwallet and slickdeals and no longer be unique."
