"DaimlerChrysler's Marriott code DCX was the merged Daimler-Chrysler entity code (1998-2007 merger). The company later split back into Daimler AG and Chrysler. The code likely remains active in Marriott GDS with one of the successor company relationships. Auto industry codes at Marriott carry medium risk — properties near Auburn Hills MI (Chrysler HQ) and Stuttgart recognize auto company employees. FlyerTalk notes that European Marriotts verify auto company codes more frequently than US properties."

"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 as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."
