"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 work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."

"I always see people saying that they aren’t able to do mobile check in. I’ve only stayed at two Marriott hotels where I tried to do mobile check in ( both of them never been to before) and they both let me without having to go to the front desk which I was really happy about because I had lost my ID and didn’t know how I was going to check in. Also I think I only had about 20 nights at the time, I usually stay with my boyfriend because he’s titanium."
