Duration ladder: fitting a session into a layover
The duration ladder is the fixed rate list behind every booking: length, one or two therapists and one guest or a couple set the price, never the flight.
Airfares move with the date, the cabin and the hour you search. The ladder does not move at all. It is a short list of session lengths, each with one price, applied identically to a room on the terminal's doorstep and one on the canal ring, whether the session starts after lunch or before dawn.
The rows
- one guest, one therapist: the base row, with ninety minutes at one and a half times the hour, two hours at twice it, three hours at three times, and the eight-hour overnight as a single fixed sum;
- a couple sharing one therapist: double the base row at every length, the night included;
- one guest with two therapists, the four-hand format: the same doubled hours, with the night billed as eight of those doubled hours;
- a couple with two therapists: four times the base row by the hour, and twice the four-hand night.
Every hour past the third is charged at its own row's hourly figure, so a fourth hour adds one more base hour for a single guest with one therapist and four base hours for a couple with two. The same table is printed inside each therapist profile.
Picking a rung from the itinerary
Travellers rarely choose a length for its own sake. They choose it from the gap they have. A long connection with a day room leaves space for ninety minutes and a shower without watching the clock. A landing at 22:00 with a meeting at nine allows a firm two hours and a proper sleep afterwards. A missed connection that has turned into a whole night at an airport hotel is where the overnight enters the conversation. Leave margin at both ends: the rung counts the time with her, not the minutes you need to dress, repack and reach the gate. The layover entry shows how to measure that margin.
The rung and the deposit
Length also decides part of how a booking is paid. Three hours or more always confirms with half in advance: one guest with one therapist sends half of three base hours up front, one guest with a pair sends half of six, and a couple with a pair sends half of twelve. Shorter rungs carry the deposit too whenever another condition applies, among them any booking at Schiphol or an airport hotel and any first booking. Each therapist's profile carries the current rates, and the deposit entry lists every condition.
