"VISA's Marriott code VSA is a financial technology code. VISA HQ is in Foster City CA (San Francisco Bay Area). Finance/fintech codes at Bay Area Marriott properties carry moderate scrutiny. hotelcorporatecodes.com: "⚠️ Sometimes." VISA has 20,000+ global employees — significant but manageable for hotel verification at full-service properties. No VSA-specific denial documented in FlyerTalk. Standard finance-sector Medium calibration applies."

"I have a close friend who is a GM at a Marriott property in a fairly large US city (top 25 metro population). Their opinion is basically, "Hey, it's business. I'm not turning away a paying guest if they don't have the right ID." In this person's younger days as a front desk agent, they enjoyed catching people trying to use a corporate rate that the guest was not entitled to. As they became higher up and saw the books, occupancy rates, etc... Corp ID's became far less important than filling rooms."

"I swear the front desk employees are trained to resist and encouraged to lie. They try to save the rooms for members with higher status or complainers. I've booked King rooms and they'll assign me a double or a queen. The first rep will tell me they're fully booked and there's nothing they can do. But once transferred to a manager, King rooms magically appear!"
