Ninety Minutes, and the Twenty That Do Nothing
The opening twenty minutes of a slow session look as though very little is happening, and that stretch does not shrink with the booking. It is the reason an hour is so often the wrong length to choose.
Guests choosing a length almost always weigh it as though the session were uniform: twice as long, twice as much of the same thing. It is not uniform. It has a front section that does a particular job, and the length of that section does not change with the booking.
What the twenty minutes are for
A body that has spent a day walking around a foreign city arrives on the bed braced. Not consciously; it is simply what a body does after hours of narrow pavements, unfamiliar traffic and low-level vigilance. Shoulders sit high, the jaw is doing something, breathing is shallower than it should be.
Nothing useful can be done with that. Slow, warm, unhurried work in the first stretch is not a preamble to the session; it is the part that persuades a nervous system it can stand down. It looks uneventful from the inside, which is exactly why guests misprice it.
Why an hour often ends at the wrong moment
Twenty minutes out of sixty is a third of the booking. What is left is a decent forty minutes, and that is a real session that plenty of people are right to book. But the common report from a sixty minute slow booking is that it finished at about the point it was becoming what it was booked for, and that is arithmetic rather than bad luck.
At ninety, the same twenty minutes is a fifth. What follows is long enough that neither person is managing the clock, and the tempo stops being something either of you is maintaining deliberately.
Reading the step as money
An hour is EUR 180 and ninety minutes is EUR 270, so the step costs EUR 90. Two hours is EUR 360, so the next step costs the same EUR 90. Judged by what each one changes about the evening, the first step buys considerably more than the second, and a guest choosing between sixty and ninety is making a bigger decision than a guest choosing between ninety and a hundred and twenty.
Past two hours the character changes again rather than simply extending, which is a different decision and not a matter of getting more of the same. The eight hour night is a different thing altogether.
Things that lengthen the front section
A cold room, by a considerable margin; a body that is cold does not stop bracing at all, and the warming stretch simply runs on. A bright overhead light, for the same reason in a different register. A phone that lights the ceiling every few minutes. And a guest who lay down before she arrived and got up again at the knock, which resets the whole thing.
All four are handled in the forty to sixty minutes between the confirmed booking and the door, and handling them is worth more than any amount of technique afterwards.
Deciding without a discussion
Nobody is talked upwards here and there is no upselling in the thread. If you cannot settle it, name the two lengths you are choosing between and take the longer one; that is the standing advice and it is given because the regret runs in one direction only. A booking already agreed can also be shortened by a line sent before she leaves, which simply makes it a shorter booking at the shorter figure.
The exception
A returning guest, in a warm room he has already used for this, with the lamp already where he wants it, skips a good part of the front section. That guest can book an hour and get an hour. It is the first booking in an unfamiliar room at the end of a long day that wants the extra thirty minutes.
What the front section is not
It is not a warm-up in the athletic sense and nothing is being prepared for anything. Framing it that way leads guests to treat it as overhead, something to be got through, which is self-defeating: a person waiting for the session to start is a person still on duty, and the waiting is itself the thing that lengthens the stretch.
The better framing is that the first twenty minutes are the session, running at the tempo the rest of it will keep. Nothing changes gear later. If a guest is expecting a moment where the real part begins, he will spend the hour waiting for a signal that is not coming, and afterwards report that it was pleasant but that nothing much happened, which is a description of an hour spent listening for a starting gun.
