The duration ladder is the house's fixed list of booking lengths, from a single hour for one client with one therapist up to the overnight a couple books with two.
Every booking with the house is priced from one short list, called here the ladder because each rung is a length of time and the price climbs with it. The technique does not change the figure, the district does not change it and the hour of the night does not change it. What changes the price is how long the session runs, whether one therapist or two are booked, and whether the booking is for one client or a couple.
A couple sharing one therapist pays twice the single figures at each of those lengths, and twice the fixed fee for the overnight. A single client with two therapists, the four-hand booking, pays those same doubled amounts across the four hourly lengths, with a night fee of its own. A couple with two therapists pays four times the single figures, and twice the four-hand fee for the night. On every row, each hour past the third is charged at that row's hourly rate.
The ladder is linear up to three hours, then it flattens into an hourly add-on, and then the overnight replaces the count altogether. A buyer weighing a long evening against a full night should compare the two directly, because once five or six hours have been counted one by one, the fixed night is where the arithmetic starts to favour the longer format.
The rung chosen also decides whether a deposit applies. Any session of three hours or more is confirmed with half the fee in advance, as is every overnight and every two-therapist booking. A one- or two-hour session booked for the same day by a returning client is the single case paid wholly on arrival. The deposit entry lists the other conditions.
A two-hour session booked for the following afternoon, for example, carries a deposit of half its fee because it was reserved more than a day ahead. Each therapist's profile prints the current table in full, and the FAQ answers the questions buyers most often ask about lengths.
