"One FlyerTalk user reported using the IBM corporate code for 14 years, 80–100+ nights a year, and never once being asked for ID. However, Newark Airport Marriott religiously asks for ID, requiring a letter from IBM stating you are a legitimate contractor. Consultants who tried to use a former employer's IBM code and couldn't produce valid ID were charged the full going rate of ~$300 instead of the corporate rate of ~$100."

"I always see people saying that they aren’t able to do mobile check in. I’ve only stayed at two Marriott hotels where I tried to do mobile check in ( both of them never been to before) and they both let me without having to go to the front desk which I was really happy about because I had lost my ID and didn’t know how I was going to check in. Also I think I only had about 20 nights at the time, I usually stay with my boyfriend because he’s titanium."

"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 !!"
