How do you get the world’s largest hotel chain to offer an acceptable refund?

According to this <a href="https://en.wikipedia.org/wiki/Marriott_International" rel="noopener ugc nofollow" target="_blank">Wikipedia article</a>, “Marriott is the largest hotel chain in the world by the number of available rooms. With 31 brands across 8,000 properties containing 1,423,044 rooms in 139 countries and territories. Of these 8,000 properties, 2,149 are operated by Marriott, and 5,493 are operated by others pursuant to franchise agreements.” So not short of a few quid/euros then. The Moxy Vienna Airport hotel is one of those franchises and operated by Bierwith & Kluth Hotel Management GmbH. I enjoyed reading ‘Empathy’ is of B&K’s values. <a href="https://jonrhodes.medium.com/how-do-you-get-the-worlds-largest-hotel-chain-to-offer-an-acceptable-refund-c2e2b2f923db">Learn More</a>
