"IBS (Intel) is confirmed in AeroPenguin's Marriott code list. hotelcorporatecodes.com lists IBS at 10-15% discount, "⚠️ Sometimes" verification. FlyerTalk enforcement thread context: one member noted "IBM used it 14 years, 80-100 nights/year, never asked once" — but IBM is a distinct code with different discount depth. Intel's IBS at 10-15% discount is in the "low-pressure" zone where hotels rarely verify. One FlyerTalk moderator noted: "the primary trigger for audit is the rate delta — if the corporate rate is close to BAR, staff see no reason to challenge." IBS falls in this low-delta category at most US domestic properties."

"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."

"My employer does not have a corporate rate but when I'm consulting for a company that does, I use theirs. I've only been challenged for identification once. In that one situation I explained the consulting arrangement, and the desk clerk accepted it without a badge or business card (neither of which I had anyway)."
