"Alibaba's Marriott code A7A is for the Chinese e-commerce and technology giant. Alibaba employees primarily carry Chinese company-issued credentials which Western hotel front desk staff are less familiar with verifying. FlyerTalk's corporate code thread notes that Chinese tech company codes at US and European properties face a different verification challenge: staff may request proof but be unable to assess the validity of Chinese corporate ID cards. Marriott's rate desk has documented Alibaba as a monitored account given the company's rapid growth and high travel volume. High risk due to systematic verification challenges."

"I dont even have a corporate ID or badge lol, i started my job remote and I’ve never even been to a corporate building yet despite having made five or six business trips in the last two months and never been asked to show proof i work for the company i work for. So im gonna place my bet on no, altho if you have a family with you they might question whether you’re actually on a business trip."

"I don’t think it’s ever ok to yell at anyone in customer service. That said, I do understand the frustration as someone who’s stayed over 1,000 nights in hotels, and have come across many properties who do simply not want to upgrade and/or just follow corporate policies at all for that matter. I had a Hyatt try to charge me a resort fee on a points stay as a globalist. Point blank that’s not how it works. They don’t get to change that rule at the property level. I’ve stayed at properties that had over 40 suites available and refused to upgrade. So, OP, your property with only 4 suites is very different than many. But just to be fair, a lot of us have experienced many shady properties and being outright lied to by managers."
