"FlyerTalk directly documents Grand Hyatt Tokyo staff awareness: "Memo from WoH Concierge to GH Tokyo: Beware of guests using CS code without proper ID" — implying the property is actively watching for unauthorized Credit Suisse code use. A Hyatt Regency Tsim Sha Tsui guest received a pre-arrival email requesting verification, resolved only by replying from a CS corporate email. Financial-sector codes are the highest-risk Hyatt category. Credit Suisse (now UBS following 2023 acquisition) triggers additional suspicion because the acquiring company may no longer honor old CS codes."

"I use a code for most bookings and have never been asked for an ID. I have an ID but it does not have our company name on it since it’s also my badge to access the building and we have one office in our city. If it ever came down to it I can send them an email on the spot from my @company.com email"

"“Im a remote worker so I don’t have a badge. Our IT department also decided last month that we can’t have any company material on our personal phones. I used to be able to show my Outlook with my @cocacola.com address but now I can’t. I used to be able to wake up and check my email to see if I really had to get out of bed, but now I can’t. It’s absurd.” Keep rambling and they’ll probably just check you in lol"
