"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."

"Out of my decades of being a globalist, PH Sydney was the ONLY property that asked me to show my corporate rate credentials at check in. I found services to be hit and miss. When I checked out at 5:30 am to catch an early flight, the front desk asked me if I want any pastry and coffee to go. Less than a minute later, a flat white and warm chocolate croissant were given to me."

"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"
