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. If you’re still feeling guilty read this: http://en.wikipedia.org/wiki/The_Hyatt_100

      I'm and IBMer and the answer for me is NO. The people at the desk don't know and don't care. This is no way of tracking you.

      Just used the IBM code in Columbia SC at the Hyatt. The Operations Manager sent me a email the day of arrival. She stated that she see's that I am using the IBM rate but did not use the IBM booking tool (special internal travel network). Persons not associated with IBM were using the code. IBM & the Hyatt now require a valid company ID to be shown when reservations are made outside of the IBM booking tool. If no ID can be provided the rate will change to the best available rate. Luckily I was prepared for this as I followed the advice in this thread by having business cards made for numerous companies. When I got to the front desk I was asked for my ID. I gave the clerk the business card, she looked at it and completed my check in with no problems.

    I had no luck with any Hyatt codes. Was planning a trip to Disneyland in CA and nothing seems to work. Any help is appreciated.

    On another note, I want to say thank you for the person who created this site and for sharing the codes. Its about time something like this became available. I agree with what I read earlier about why the hell do big corporate ppl get massive discounts when they clearly can afford it. Blows my mind nd get me frustrated. More when I have to work over time just to pay the debt we created. Its an uphill struggle these days and something like this site is like a breath of fresh air. But like i said earlier, I tried a lot of these codes and none seem to work for me. I was trying the Hyatt ones but really, any hotel would do right about now.

    I hope somebody reads this board before months have gone by. As I search for a new home, I've had to stay in hotels and my credit card is nearing the limit just with hotel charges averaging $75 a night, and that's. With any discount I can find like F&F at Holiday Inn for 20% off.

    Going to try corp code to get decent rate in Southern CA. Any helpful tips greatly appreciated.
