"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 have stayed 100s of times with various corporate rates (including Japan) and the only hotel that has asked is W hotels. Even then they didn’t push much. I have been a consultant for 20 years and many clients require you to use their rates when they are paying the bill. The hotel doesn’t have an up to date list of every employee that works for a company globally. The woman at the W said “I don’t really care, just show me anything on your phone that says your name and that company. You can type an email now “."

"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.

But once transferred to a manager, King rooms magically appear!"
