"JOH is listed on FlyerTalk's "List of publicly usable Marriott reservation codes" as one of the widely-circulated three-letter ticker codes. A self-identified J&J employee was cautioned: "the code is not meant to be shared publicly — the proper way to get it is to email someone from your company." hotelcorporatecodes.com lists JOH at 10-15% discount with "⚠️ Sometimes" verification. FlyerTalk general pattern: pharma/healthcare corporate codes at full-service Marriott yield ~30% chance of check at urban US properties, near-certain in Europe/Asia, essentially zero at select-service. The code's ticker-symbol obviousness means it circulates widely, which has historically triggered audit flags at some properties."

"I have stayed 100s of times with various corporate rates (including Japan) and the only hotel that has asked is W hotels. Even then they didn’t push much. I have been a consultant for 20 years and many clients require you to use their rates when they are paying the bill. The hotel doesn’t have an up to date list of every employee that works for a company globally. The woman at the W said “I don’t really care, just show me anything on your phone that says your name and that company. You can type an email now “."

"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."
