Honestly, if hotels cannot or do not want to honour these benefits for Elites, perhaps for luxury brands Marriott could consider introducing Titanium or Ambassador only benefits for luxury brands. I know the T&Cs do not promise these benefits but.... as an ambassador member travelling for work, why would I go the extra mile and stay at Marriott properties like the Prince Kioicho if I have more convenient non-Marriott properties closer by to my offices? What is the benefit then, just the points?
