> My last hotel only had a single escalator, which went up during check-in hours and down during check-out hours.
Im unsure if this contradicts metaphysics or physics, but then it could do each way only once, requiring a lot of stair walking. Perhaps, however, you omitted the possibility that it only accepted passengers up OR down depending on time.

In some lesser used buildings in Japan I have seen escalators with sensors at top and bottom which stop completely when no one is on and change direction when a person tries to ascend or descend. It must also sense when riders are present to prevent changing direction then. I haven’t seen those elsewhere. Many newer transit gates in Japan also work as both entry and exit gates changing based on demand.
