A few years ago, I was midway through a trip around the globe and had a stopover in an airport I'd never visited before. I was about 20 hours into my journey, tired, hungry, and in desperate need of sleep. Unfortunately, my flights had all been delayed, and the airport had essentially shut down. My only option was to stay in one of the hotels supposedly attached to the airport. But finding one of these hotels was easier said than done. After asking around a few times, I finally found a sign that gave me hope. I followed the arrows until I was led into a large, empty room.
