"Applied Materials' code APP appears in Marriott corporate code lists but has minimal community discussion. A FlyerTalk comment notes that some codes "are old and may not be valid, and some may require ID of some sort," and that rates are "widely offered and hard to check ID" particularly when extended to company retirees. Applied Materials is a major Silicon Valley semiconductor equipment company; Bay Area hotel density reduces the novelty of tech company codes in that market."

"I wouldn’t mind that at all. Credit Card companies have super weak security and it’s very easy to defraud them - they just pay our money back, and counts that as losses so we’ll sure up about it and keep using the cards What I mind is that the mobile check-in is basically a lie. Marriott is deceiving me. Random hypothetical people that might or might not stole my credit card are not. Hilton works just fine btw"

"I work front desk and it seems like management is really pushing to check IDs for any special rate. Personally im lazy and also don’t care that much to start a confrontation so I only verify govt rates and employee rates, but yes it is being enforced more harshly. Corporate rates I guess are easy to find online and thus abused. Again, I don’t care that much because they’re still pricey anyway !!"
