"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 !!"

"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 “."
