This guide answers one question, asked several times a night in slightly different words. Is it too late. Have I missed it. Is anything still possible at this hour.
The short answer is no hour is too late, because the roster runs through all of them. The longer answer is more useful, because two things genuinely do change as the night goes on, and knowing which two lets you make a better booking instead of an anxious one.
The two real constraints
Choice narrows. Forty-five therapists work from the roster and each of them keeps her own hours. More keep eleven at night than keep two in the morning, and more keep two than keep five. At no point does the number reach zero, which is why a booking at any hour is possible, but the group you are choosing from is smaller at four than at midnight. This is the constraint people never anticipate.
Your own judgement narrows. This is the constraint people never admit to. Decisions made at three in the morning at the end of a nineteen hour day are consistently worse than the same decisions made at eleven: shorter bookings than wanted, vaguer messages, entry details left out, and the occasional booking that a guest is too tired to enjoy.
Notice what is not on the list. The fee stays where it is. The arrival window holds. The rule about what goes ahead pays no attention to the hour either. Availability does not disappear, and the willingness of anyone to take a booking at an unusual hour does not come into it at all.
Hour by hour
Ten until midnight
The easiest stretch of the night and the one most people should use. The roster is at its widest, meaning a specific therapist is a realistic request rather than a hopeful one. Your judgement is intact, so the length you choose is likely to be the length you wanted. And it is still the same day, so a returning client asking for an hour or two at a city address pays the whole fee at the door with nothing going ahead.
If you already suspect at eleven that the night is going this way, this is the moment to write. It costs nothing to decide early and it buys the whole of the choice.
Midnight until two
The busiest window for messages, particularly at weekends. Still wide open, still entirely ordinary, but this is where the evening's second wave lands and where a specific request starts to compete with other requests. A general request is straightforward. A particular therapist on a Saturday at one is where you start to notice the difference.
Buildings are at their most locked around this time. Street doors have shut, lifts want keycards. Put the entrance in the first message.
Two until four
The quietest and in many ways the most pleasant part of the night. Message volume has dropped off sharply, buildings have gone silent, and corridors are empty. Three in the morning is frequently easier than midnight for exactly that reason, which surprises almost everyone who asks. The roster is narrower than at midnight but the competition for it is much lower.
This is the stretch where length matters most. The reflex is to book the minimum because it is late; the reflex is usually wrong. The guide to three in the morning covers the hour in detail.
Four until seven
The narrowest stretch for choice and the one where flexibility about who comes is worth more than anything else. It is also the stretch where the light becomes a factor, which in June means before five and in December means well past eight.
Two entirely different guests book here: one at the end of a long evening, one at the start of a day on another continent's clock. They want opposite things, and the dawn guide takes both apart.
Seven until nine
Not a late booking at all any more, though it is often made by people who have been awake all night. Buildings start moving, corridors stop being quiet, and it becomes an ordinary morning booking with a long history behind it.
What does not change at any hour
The fee, first. One therapist for one guest is EUR 180 an hour on every day and at every hour of it, rising to EUR 270 for ninety minutes, EUR 360 for two hours and EUR 540 for three, with any further hour at EUR 180. Where a second therapist joins, or a second guest, the hourly figure becomes EUR 360; where there are two of each it is EUR 720. A whole night for one guest with one therapist is EUR 1,250. Nothing is added for darkness, for a Saturday or for the journey inside the ring, and the figures live in the profiles on the roster.
What actually stops a booking
Almost nothing, and it is worth naming the short list rather than leaving it to the imagination.
A room outside Amsterdam stops one. The house covers central Amsterdam, with Schiphol and the airport hotels arranged separately, and nothing beyond that at any hour. No town near the city, however short the drive looks on a map.
An address that cannot be reached stops one, which in practice means a locked building with no code given and nobody answering a phone. That is the failure mode this whole guide keeps returning to because it is the only common one.
A guest who cannot satisfy the therapist at the door that everyone present is twenty-one or over stops one, and that decision belongs to her alone. She may ask to see a passport or another photo document, reads it, hands it straight back, and nothing from it is copied, photographed or written down.
Nothing else on a normal night does. Not the hour, not the day, not how short the notice is, and not the fact that you have never booked before.
The arrival window, second. Forty to sixty minutes from a confirmed booking to a knock, identical in every central neighbourhood, at eleven at night and at half past four alike. It is counted from confirmation rather than from your first message, and on a booking that carries a deposit she sets off once that has cleared. Schiphol and the airport hotels sit outside it and are arranged separately, with the journey time agreed before anything is fixed.
The deposit rule, third. Half goes ahead on a first booking, an overnight, a two-therapist booking, an airport hotel booking, a peak date, a session of three hours or more, and anything arranged more than twenty-four hours out. Where a client has booked before, wants one or two hours later that same day and is at an address in the city, the entire fee waits until she arrives. No hour of the night appears anywhere in that list.
The question behind the question
Most people asking whether it is too late are really asking something else: whether the hour makes them a nuisance. It does not. A booking at three is an ordinary booking, made by people who work nights, people whose clocks belong on another continent, people whose evening ran long, and people who simply could not sleep. Nobody is doing anyone a favour and there is no apology owed for the hour.
It is also worth knowing that the question gets asked most often by people who have never booked at all, and that a first booking is the one category where something does change: half the fee goes ahead, whatever the hour and however short the notice. That is not a late-night rule and it is not about the hour you happened to write at. It applies equally to a first booking made for a Tuesday afternoon three weeks from now, and it stops applying the moment you have booked once.
The one thing worth being honest about is your own state rather than the clock. A guest who has been awake for twenty hours and books three hours at half past three may find that the evening had already spent what the session needed. That is not a reason to book nothing. It is a reason to book earlier when you can, and to be realistic about length when you cannot.
If it really is late, write this
Four lines and nothing more. The hour you want, in numbers. The length, from the ladder. The format. The area, with the floor and anything the entrance needs after hours, since a coded street door at three in the morning is the one thing that genuinely delays an arrival. Add whether it is one guest or two.
Send the exact room or apartment number once the booking is confirmed rather than in the first message, keep the phone face up with the sound on through the arrival window, and count the balance out while you wait. The note on writing when you are tired covers what usually goes missing.
