Choosing a length for a daytime booking

There are five rungs: sixty minutes, ninety minutes, two hours, three hours, and the block of eight. With one guest and one therapist the lower four rungs rise strictly with the clock, so ninety minutes weighs one and a half hours' fee and three hours weighs three, whereas the eight hour block stands on a figure of its own. Put a second therapist on a rung and it doubles; seat a second guest beside the first with one therapist and it doubles likewise; two guests with two therapists lift it fourfold. Every figure is on the profiles in full.

Why an hour is shorter than it sounds

The booked time starts when she is in the room, not when she knocks, but the first few minutes go on the practical part: the balance, the bag, a word about what the session will and will not include. Sixty minutes is a real hour of contact only if you are content for the whole of it to be that. Ninety is the rung most guests settle on after the first booking, and the step from sixty to ninety adds half of an hour's fee.

The afternoon case for three hours

Three hours is awkward to place in an evening, because it eats the evening. In the middle of a free day it is the easiest rung of all to fit: begin at one, finish at four, and the whole of the evening is still ahead of you. It also crosses the deposit threshold, so half of the three hour fee travels first whatever else is true of the booking.

Extending on the day

Adding time once she is there depends entirely on whether the rest of her afternoon allows it, and it is quoted before it begins rather than tallied up afterwards. Ask early in the hour rather than at the end of it. Shortening works the other way: decide before she leaves and the booking simply becomes the shorter rung, but a session closed early once it has started stays payable in full.
