Completeness is the rarest quality in hospitality and the hardest to fake. Most houses have a peak — a restaurant, a spa, a view — and a trough somewhere behind it. This collection is for the ones without a trough.
The sensor reads across departments rather than at them. A house is admitted when its published material shows the same intent everywhere: the room described with the care given to the kitchen, the arrival given the care given to the suite. A single department carrying the rest is a reason for exclusion, not a reason to admit.
The question is declared, the sensor is published, and the ground travels with the verdict.
