Since this is a semi-private forum and probably not searchable via google.com I thought I'd dump a bunch of the codes I found here in case others might make use of them. The obvious caveats:
- You are probably not entitled to use any of these. If this causes you emotional problems, then don't use them
- You could be challenged when you check in (more likely internationally). If this scares you, then don't use them
- They may not work for you. Each company negotiates discounts at various specific properties and you won't see a discount at other locations. YMMV
(hint: find companies that have locations nearby the hotels you want to stay at)
- Some rates may cause you to be challenged every time you check in. Feel free to figure out which ones those are yourself. Is the rate just too low to feel comfortable booking it? Then don't use it.
- If you use different corporate rates every time you book at the same or maybe multiple locations they might notice this and challenge you or even do something more drastic. You assume all risk using these codes.
- There are some rates that are not in this list for one reason or another. This isn't a complete list.
For each company there are two numbers. A number starting with an N (optional) which works for Hilton/Conrad properties. And a number after a slash that works at the other Hilton properties. Yes this means you'll sometimes have to do two searches.
