Here’s a consolidated list for the Marriott. Every code below is confirmed to work as of today. I have them more or less in order of what has worked best for me. It would be great if someone could help add to my list.


General Electric GEE
Siemens SIE
Ford FRD
General Motors GMC
Accenture ACC
Pepsi PEP

A few general comments:

1. GE works the best just about anywhere followed by IBM, but sometimes the Siemens and Samsung rates will amaze you. I just got 70% off at the Grand Hyatt in HK with Samsung for example.

2. I have used these probably 40 times in 10 countries and I get asked for ID 50% of the time. I have a stack of business cards I printed myself and they have worked 100% of the time. Never had a problem, even at times when I thought I may. For example, I have stayed at hotels where I got an exceptional discount to find out it was because the office was right next door (Intercontinental Beijing / IBM) and my self printed cards were not questioned.

3. I don’t know about others experience, but I get upgraded 25% of the time using these codes and being “with” these corporations. I still laugh when I hear, “Sir, since you with company X I upgraded you to a suite”. My best ever was a two-room suite for $81 a night (IBM discount).

4. On a personal note, this ethical debate is total crap. These hotels are obviously making money at these rates, and why should an executive of a multi-billion dollar corporation get a discount and then an individual pays more? You’re leveling the playing field.
