"Student (Enactus) Marriott code OXD is a student discount code for Enactus, a non-profit supporting student entrepreneurs. Student discount codes at Marriott require proof of current student enrollment — typically a valid student ID or university email verification. FlyerTalk's discussion of student hotel rates: "Student rates at Marriott almost always require showing a valid student ID at check-in — unlike corporate codes where enforcement is discretionary, student discount verification is fairly consistent across properties." The Enactus connection means participants must also prove program affiliation."

"I have been asked by the front desk on a few occasions but more often than not they don’t ask. I luckily used my corporate rate in the instances they asked: however, they can charge the rack rate which can be much higher than what you are prepared to pay so I would just go in with open eyes."

"I used the Google rate for the Ritz in Tokyo and was asked to send an e-mail from a corporate account. I don't work for Google so I just told them to charge me the regular room rate. The front desk person said okay. When I checked out, they had kept the corporate rate."
