"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 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 am very rarely asked to prove my eligibility for a rate...but they have every right to ask and if you can't produce it, you will be re-rated to the current rate, which is often even higher and there is no guarantee points rooms will be available. Doing online check in rarely helps this as most properties don't actually do online anyway - especially to people who are not returning guests to the property or elite. You are taking a gamble. One that is likely to be fine. But understand you are intentionally breaking the terms of the bonvoy program and if someone really cared, there can be consequences."
