"Apple (alt) Marriott code APC is a secondary Apple corporate code, alongside the primary APL code. Apple's primary code APL is documented as triggering heightened enforcement within 5 miles of Apple HQ in Cupertino — "hotels that handle hundreds of Apple travelers a week are intimately familiar with Apple corporate ID badges." The alt code APC may be routed through different GDS channels but Apple's code presence at Silicon Valley Marriotts is well-established. No APC-specific denial documented; enforcement pattern mirrors the primary APL code."

"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 !!"

"My last couple of corporate RFID cards had no company name on them for security purposes. My current company doesn’t do business cards. I use my Bonvoy card for corporate travel to get the points. I’d have to write them an email standing at the check in desk, I guess."
