"A Fishbowl post titled "Anyone ever use another company's corporate discount code for Marriott? XOM Exxon code is showing a significant discount" directly references this code, confirming community awareness. FlyerTalk confirms Marriott is usually strict about corporate codes: "Consultants who tried to use a former company's code were required to produce a valid company ID. Since they couldn't, they were charged the full going rate of $300 instead of the corp rate of around $100." XOM is a ticker-style code with high profile."

"I used to work night audit at a 4 diamond Marriott resort. It was me, an 80 year old valet who just slept in the cars, and a 4'11" security guard. She wouldn't check anything out because "I'm a woman. If there's someone there, they could attack me." So I, the 19 year old woman, would investigate. Guest needed towels? I brought them. I would have to go up to a computer room to run some of my reports. I occasionally had to pee, because I'm selfish like that. So whenever I was gone from the front desk, it was just unstaffed. It sucked."

"I have been asked to show some proof couple of times. I normally show my corp id but credit card with employers name on it has worked, too. As would probably just showing my laptop with employer e-mail account or whatever. My impression has been they are happy with just about anything that proves I'm working for the company whose rate I use and why wouldn't they."
