I'm bumping this up because I would like to find out if there are other discount codes besides AAA & AARP. For example, on the Marriott forum they have 7 pages of codes:

I'm not suggesting that we list corporate codes (the pros/cons of that are in the Marriott thread, although folk there have posted some corp codes).

What I'm thinking of are there other codes that would be available to everyone - for example, on the Marriott thread there are some that apply to Northeast hotels or Southwest hotels or London hotels or international hotels - they're valid promo codes & you don't have to be part of a select group or org in order to use them.

Does Hilton have similar ones? And if you have discovered any, please post them here.
