The Street Door That Locks at Eleven

Everything else in a thread is robust. A wrong house number gets sorted out in a message. A guest who says nine and means half past nine is not a problem. The entrance is different, because the failure happens at the door with nobody able to do anything about it, at exactly the moment the guest has settled the room and put his phone in a drawer.

The four ways it goes wrong

A street door that locks automatically at a set hour, so a buzzer that worked at eight does nothing at eleven. A lift that needs a keycard to reach the floor, which is standard in a good many hotels and never mentioned by guests because it is unremarkable to them. A night entrance around a side street, with the main doors closed. And a building with a staffed desk that has gone unstaffed for the night.

Each of those is trivially solved by one sentence sent in advance and genuinely awkward at the moment it happens.

What the sentence should contain

The floor and the room or apartment number, always, which does more work than anything else in the message. Then whatever is true of the entrance: which bell, whose name is on it, whether the lift wants a card, whether the front door is locked after a certain hour, and what to do if it is. Twenty words covers nearly every building in this city.

A guest who is not sure has a reliable test. Ask yourself what a visitor arriving at that hour, who has never been to the building, would have to be told. That is the sentence.

The phone is part of the entrance

A locked street door is only a problem when nobody can be reached. The single most useful preparation before an arrival is a phone left somewhere it will be seen, with the sound on, until she is actually in the room. Face down in a drawer is the right place for it during the hour and the wrong place for it during the wait.

This is the one exception to everything else this site recommends about phones, and it is worth holding onto because the two pieces of advice sit ten minutes apart.

Apartments are harder than hotels

Hotel entrances are at least consistent within a building, and a guest can usually answer the keycard question by remembering how he got upstairs himself. Short-let apartments are the awkward ones: a canal building with three bells and no names, a staircase that starts behind a second door, an entrance that is not on the street the address names.

Those are also the buildings where a guest has the least experience of arriving as a stranger, since he was shown in once and has used a code ever since. Worth thinking through properly rather than assuming it is obvious.

Why it matters more here than elsewhere

Because of what the arrival is meant to be. The whole arrangement is built so that a guest who wants a calm evening does not have to do anything social: no reception, no lobby, no conversation on the way in. A delayed arrival with messages going back and forth about a locked door undoes all of it at the last moment, and it is the one failure mode that the guest can eliminate entirely in the forty to sixty minutes he is already sitting through.

Airport hotels

Those are arranged separately in any case, with the journey time talked through and agreed before an hour is held, and the entrance question is usually simpler out there. Late night lobby access and lift cards still apply, so the same sentence is still worth sending.

The sentence, written out

For anyone who would rather copy a shape than compose one: third floor, apartment nine, the bell on the right with no name on it, and the street door locks at eleven so send a message and I will come down. Thirty words. It covers the floor, the number, which bell, the failure mode and the remedy, and it removes every version of the problem described above.

For a hotel: eighth floor, room eight hundred and four, the lift needs a room card after ten so please message from the lobby. Twenty-five words, same job. Neither of those is a long sentence and neither requires knowing anything unusual about the building. It is simply the information a stranger arriving at that hour would need, written down once, in the same message as the hour and the length.
