The bag is the single, unremarkable shoulder bag a therapist carries into a hotel, holding everything the reservation needs and taking everything used away again.
Nothing about an arrival is more visible than luggage. A wheeled case says someone is checking in; a folding table under an arm says exactly what it is; an oversized holdall looks like a move. So the therapist carries one soft bag on one shoulder, of roughly the size people carry a work computer in, in a colour nobody would remember afterwards. In a lobby it reads as a guest's work bag, and nobody looks at it twice.
No candles: every hotel ceiling carries a smoke detector. No speaker, because most guests prefer the room's own quiet or their own music. No folding table, because the bed is the working surface in a hotel room. The guest need not supply anything the bag already covers, and in particular need not ask housekeeping for extra towels, which is itself a small note on a room's record.
The bag is the reason a visit costs a hotel room nothing. Everything that arrives in it leaves in it, so the linen trolley the following morning finds only what the hotel put there. The journal piece the weight of the bag explains why it is packed the way it is, and the morning side of the same thinking is under housekeeping.
None of this is extra on the ladder. The bag comes with every reservation at the same price, from the first hour to an overnight.
