"E&Y (alt) Marriott code 253511 is a secondary Ernst & Young code, alongside the primary EYC code. Fishbowl posts from Big 4 staff: "How do I use the Acc or E&Y codes at Marriott and get around the ID check piece?" — confirming that consulting firm ID checks are a well-known friction point. The same risk profile applies to secondary codes: US select-service essentially never checks; US full-service 10-20%; international meaningfully higher. EY (Ernst & Young) branded itself as EY globally in 2013 — some properties may still see "Ernst & Young" in the code description."

"I had to change my email to my personal email account. My IT sucks, I have had so many joe.smith1 to joe.smith9 at my corporate name dot Com. Why I like to get my folio in person and on my email. Miss a receipt and your expense report gets rejected. Only been asked once for corporate proff, but I am nice to the staff and explain what's going on before they get a chance to ask. IT still has not figured out how to link everything to Concur for hotels. And it's a huge company"

"I wouldn’t mind that at all. Credit Card companies have super weak security and it’s very easy to defraud them - they just pay our money back, and counts that as losses so we’ll sure up about it and keep using the cards What I mind is that the mobile check-in is basically a lie. Marriott is deceiving me. Random hypothetical people that might or might not stole my credit card are not. Hilton works just fine btw"
