Everything about a late booking gets planned except the end of it. The hour is chosen, the length is chosen, the format is chosen, the building is explained. Then the session finishes at half past three and there is an hour that nobody considered, and that hour does a surprising amount of work on how the night is remembered the following afternoon.
It is worth ten minutes of forethought, and the forethought is almost entirely about the room.
The shower is not optional
Take it, take it hot, and do not rush it. Oil-based work leaves oil, and sleeping in it means waking up on sheets you do not want to be on. More usefully, the temperature swing of a hot shower followed by a cool room is one of the more reliable ways of making a body want to sleep, which is exactly the direction you want to be pushed at four in the morning.
Wash your hair if there was any work on the scalp or the neck, however much you do not feel like it. This is the single most common regret in the category, and it is a small one, but it is real.
The room, before she arrives rather than after
Three things, all faster to do at midnight than at four.
Close the curtains properly. Not most of the way. In summer the light here starts before five and a gap of ten centimetres is enough to end a night early, which is a particularly unkind outcome after a session that finished at three.
Turn the phone over and take the alarm off if there is nothing that needs one. If something does need one, set it before the booking rather than afterwards, when you will be doing arithmetic you are not equipped for.
Put water somewhere you can reach without standing up. Trivial, and the thing people most often wish they had done.
What the body is doing
A long unhurried session leaves most people somewhere between very relaxed and genuinely sleepy, and the window for using that is not enormous. Half an hour, roughly. Spent on a shower and getting into bed, it lands well. Spent on a phone in a lit room, it closes, and what follows is the specific frustration of lying awake at half past four having been half asleep at four.
So the order matters more than anything else: shower, dark, bed, nothing. Not shower, phone, some food, one more thing, bed.
The morning it produces
Be realistic about it. A session that ends at three thirty and a sleep that starts at four does not produce a nine o'clock morning, and pretending otherwise is how a good night turns into a bad day. If something in the morning is immovable, the length of the booking was the decision, not the bedtime, and it should have been made earlier in the evening rather than argued with at dawn.
Where there is nothing immovable, the right plan is no plan. Sleep until it ends on its own. Eat something proper when it does. Most people find the day after a long late session is unusually good if it is allowed to start late and unusually rough if it is not, and that is a scheduling question rather than a massage one.
If sleep does not come
Occasionally it does not, particularly for a guest whose clock belongs somewhere else. Do not fight it in a dark room for two hours. Get up, keep the light low, do something dull, and let it arrive. And if the pattern is familiar, if you are three days into a trip from another continent and four in the morning is simply your afternoon, then the booking itself should probably be shaped differently next time: later, longer, ending with the light rather than in the middle of the dark. The dawn guide sets out what that looks like.
One thing that is not your problem
The end of the visit itself. The fee is settled at the door on arrival, before the session, so there is nothing to sort out afterwards, no arithmetic, and nothing to do at the end except say goodnight. That is deliberate, and the note on the balance explains why the money sits at the front of a visit rather than the back. The last ten minutes of a late booking should belong to the shower and the curtains, not to a wallet.
