Rescheduling, and the one free move
A booking can be moved once at no cost, provided the request reaches the thread more than a day ahead and the new date falls inside the following fortnight.
Plans on a city break move constantly, so the first change of date is free and is not treated as a favour. Two conditions attach to it. The request has to arrive more than twenty-four hours before the agreed time, and the new date has to sit inside the next fourteen days.
What travels and what does not
Where both conditions hold, the first half moves across to the new date untouched and nothing is recalculated. Where they do not, the move is read on the notice scale exactly as a cancellation sent at that moment would be, and whatever the scale does not keep travels on. A second move is measured the same way, whenever it is asked for.
Moving rather than cancelling
A guest whose evening collapsed but whose trip continues is nearly always better off moving it. The message is shorter, nothing is lost, and there is no arithmetic. Say the new date in the same line as the request rather than asking whether a move is possible first, which turns one message into three.
Changing the shape instead of the date
Shortening a booking, dropping the second therapist or swapping the format is not a move at all; it is simply a different booking written down, and the figure follows the new one. The same applies to adding an hour, provided it is asked for before she leaves. Changing the name is also ordinary, with the caveat that no substitute is put forward for you: the reply says who on the roster is free that evening and the choice stays with you.
