"Stanford University's Marriott code 349097 is an academic institutional code. University codes at Marriott select-service and full-service properties are rarely scrutinized. Stanford's Silicon Valley presence means nearby Marriott properties are familiar with the code, but academic corporate rates are not high-value enough to trigger enforcement. No verification-denial cases documented in any public forum."

"Same- we stay at a very large Jw often just for a quick get away and have gotten to know a few of the staff. We’ve checked in numerous times and have been told there aren’t any upgrades - I’m Platinum. No worries, we’re just happy to be on vacation for a few days. Shortly after we’ve seen a specific front desk agent that is always friendly with us and she has upgraded us (yes, after we’ve checked in) at least three times…. And mentioned as she’s doing it, “idk why they didn’t upgrade you…. “ we never asked her since we were already checked in and we’re fine with the regular room. But certainly, a suite is a nice upgrade and very much enjoyed."

"I have never been asked and I have 51 nights in a Marriott this year using our corp rate."
