"Siemens (16605) appears in the FlyerTalk Hyatt discount code master list alongside GE, IBM, and Samsung. One contributor wrote: "GE generally works best, followed by IBM, but sometimes the Siemens and Samsung rates will amaze you — 70% off at the Grand Hyatt HK with Samsung." A user claiming ~40 uses across 10 countries with similar tech-company codes: "asked for ID about 50% of the time" — primarily at Park Hyatt and Grand Hyatt properties in Asia. Hyatt Place and Hyatt House in the US: essentially never checked. Park Hyatt properties in global capitals: near-certain check."

"We just have to book under our corporate rate in Concur regardless of rate. Example in Columbus, OH our 2 preferred properties are Hilton downtown and Hilton Polaris those rooms can be $400+ a night. If I book at the Hyatt House at $199-$225 also part of our general corporate rate off BAR it will tell me I’m out of compliance for not booking our preferred hotels even though they are more. I override this all the time but that’s how it works."

"I also see a problem where (I know our company has for certain properties) Last Room Available rates which come in at the corporate rate; its not for all properties but we do have a list of those where if there is one room left, they have to give it to us at the corporate rate; other places is a certain number go at Corp rate 1 then it goes to corp rate 2 etc"
