"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."

"I swear the front desk employees are trained to resist and encouraged to lie. They try to save the rooms for members with higher status or complainers. I've booked King rooms and they'll assign me a double or a queen. The first rep will tell me they're fully booked and there's nothing they can do. But once transferred to a manager, King rooms magically appear!"

"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 !!"
