The arrival window is the forty to sixty minutes separating the office's confirmation from the therapist's knock, one span for all of central Amsterdam, with airport hotels timed apart.
The arrival window is a span, not a promised minute. From the moment the office confirms, she is at the door of any central Amsterdam address within forty to sixty minutes. The figure does not shift by neighbourhood, by hour or by day of the week; four in the morning is quoted exactly the span that early evening is.
A therapist begins her journey from wherever she is when the booking lands. A bridge swung open for a passing boat, a tram halted at a canal crossing, a closed street: the city adds and removes minutes nobody schedules. Twenty minutes of range absorbs that. A single uniform figure also avoids the false precision a district-by-district timetable would suggest.
Body-to-body rewards a prepared room, and the window is long enough to prepare one. Start with the thermostat, because a room takes longer to warm than anything else on the list. Shower. Clear the bed of cushions and throws. Set a lamp low and leave a towel by the bathroom door. Keep the phone within reach; any change of timing appears in the thread.
Airport bookings, Schiphol and its hotels, follow an hour settled in the thread and are not held to the forty-to-sixty. A booking made for a later hour or another day does not wait on the window at all; it begins at the start time agreed. The window describes bookings wanted now, and nothing else.
The page on body-to-body tonight covers same-evening requests, and the guide to preparing for a session expands the checklist above.
