My GHA Hotel Booking Appeared to Break Two Amex Offer Rules. I Still Got $100 Back.

Anyone who has used Amex Offers extensively will know that the exclusions can be as important as the headline discount.

In late 2025, I stayed at Palazzo Manfredi in Rome, overlooking the Colosseum. I had a Small Luxury Hotels of the World (SLH) Amex Offer saved to my Platinum Card and settled the hotel bill directly at reception using that card. No statement credit appeared.

The hotel was excellent, but the reservation had been made through Hilton rather than SLH. The offer required the booking to be made through SLH itself, and American Express apparently enforced that condition.

That experience was in the back of my mind when I encountered a new Minor Hotels offer: spend $300 at participating properties and receive $100 back. This time, I managed to make a booking that appeared to conflict with not one but two exclusions.

And this time, American Express paid.

The offer appeared on my US American Express Platinum Card, providing a $100 statement credit after spending at least $300 at participating Minor Hotels properties in Europe or the Americas. It was valid through Dec 27, 2026.

I was planning an October trip to Milan, where I had been investigating GHA DISCOVERY’s relatively straightforward route to top-tier Titanium status through stays at three different hotel brands.

Minor Hotels participates in GHA DISCOVERY, and Milan has several suitable properties. The NH family is particularly well represented, while Avani and Tivoli provide additional brands. Tivoli looked attractive but was too expensive to justify purely as part of a status experiment.

Avani Palazzo Moscova, however, offered a practical combination of location, price and a qualifying GHA brand. It was also listed among the properties participating in the Amex Offer. The prospect of combining a GHA qualification experiment with a $100 hotel credit was appealing.

But our Palazzo Manfredi experience meant we had to pay attention to the offer terms. Under Qualifying Purchases, American Express stated:

Reservations must be made directly through Minor Hotels online at minorhotels.com/en or by calling a participating property directly. Not valid for prepaid reservations booked online. The terms also excluded purchases made through third parties or intermediaries.

I’d originally enrolled in Minor DISCOVERY about a year earlier, when a previous Minor Hotels Amex Offer had appeared. I never got around to using that offer, but the membership remained active. Minor DISCOVERY is part of the broader GHA DISCOVERY program. My existing membership credentials also worked on the GHA website, and I’d subsequently used the same membership number in connection with a stay at Capitol Kempinski Singapore.

While planning Milan, I had both the Minor Hotels and GHA DISCOVERY websites open, comparing properties and rates. My intention was to book Avani Palazzo Moscova directly through Minor Hotels, consistent with the Amex Offer terms.

Somewhere in that process, I took a different route.

I completed the reservation through GHA DISCOVERY. I didn’t initially appreciate the distinction. It became apparent when the confirmation email arrived, carrying GHA DISCOVERY branding rather than Minor Hotels branding.

The booking was for October 16–17, 2026, at Avani Palazzo Moscova, using a GHA Special Deal Rate. The total was €300.08, comprising €272.80 for the room and €27.28 in taxes and fees. An additional city tax would be collected at the hotel. I’d also prepaid the reservation online using my American Express Platinum Card.

In other words, I had somehow managed to do precisely what the offer terms appeared to prohibit.

A few hours later, I booked a second Minor Hotels property for the same trip: NH Linate, near Milan’s airport. That confirmation arrived with entirely different branding. It came through Minor Hotels and included the reservation details within the Minor booking system. The contrast made me question whether the Avani reservation would qualify for the Amex credit. I called Minor Hotels to clarify.

The representative confirmed that the NH Linate reservation had been made directly through Minor Hotels, whereas the Avani reservation had been booked through GHA DISCOVERY.

Unfortunately, the Avani booking couldn’t then be canceled and rebooked without incurring a charge. The reservation was staying as it was.

The Avani charge appeared on my American Express account with a transaction date of October 5. The final amount was $336.81, and the merchant descriptor was:

3CPAYMENT*AVANI PALAMILANO IT

Although the booking had originated through GHA DISCOVERY, the payment clearly identified the Avani property.

That may have been significant. American Express offers frequently depend on how merchants submit transactions, and a recognizable property name could help a charge match the participating hotel list. But I didn’t know whether the booking channel or prepaid nature of the reservation would prevent the credit.

Then an email arrived from American Express:

“Good news! You used this Amex Offer.”

The notification identified the Minor Hotels Group offer and specifically named Avani Palazzo Moscova Milan Hotel. That was encouraging, although an offer-trigger email isn’t quite the same as a posted statement credit. So I kept an eye on the account.

The hotel charge was dated October 5. On October 7, American Express applied the full $100 statement credit, just two days later. The credit appeared under the Avani Palazzo Moscova merchant name.

The result was particularly interesting because the stay wasn’t scheduled to begin until October 16. American Express had credited the offer nine days before my arrival.

The economics:

No additional spending at the hotel was required to reach the offer threshold as the prepaid room charge had already exceeded $300.

The contrasting outcomes of my Palazzo Manfredi and Avani bookings suggest that the information transmitted with a hotel payment may be as important as the reservation channel itself, although I can’t establish exactly what caused either result.

For the Avani booking, the charge carried a recognizable hotel merchant descriptor. American Express may have matched that transaction to the participating property without enforcing every booking condition.

Alternatively, the way GHA and Minor Hotels process reservations and payments may have influenced the result.

The published terms remain unchanged, so I wouldn’t assume another prepaid GHA reservation into a Minor hotel will necessarily produce the same result. But for this transaction, both apparent eligibility conflicts were overcome.

The Avani booking delivered an unexpected $100 Amex Offer credit, reducing my effective room cost to $236.81, a discount of almost 30%.

What makes this interesting is the contrast with my earlier SLH experience. In Rome, paying the hotel directly wasn’t enough to overcome a booking-channel exclusion. In Milan, a prepaid GHA reservation earned the full credit despite two apparent conflicts with the offer terms.

The Avani stay is also part of a separate experiment involving GHA DISCOVERY’s route to Titanium status through stays at different brands. I’ll revisit that once the Milan stays have been completed and the loyalty activity has posted.

For now, the Amex result is settled. This time, the unexpected outcome worked in my favor.
