Ten questions asked at reception

In the hotel, on the garden level of this building, directly below the ballroom. From reception it is about forty-five paces and you never go outside.

A passport, a national identity card or a driving licence showing a date of birth. Checked on every visit, including for hotel guests. A photograph on a phone will not do.

Yes, and most regulars do it. Tell the staff on the floor before you sit down; it is written and held to for the evening.

At reception, in person. Self-exclusion is signed at the desk and takes effect that evening, and it is lifted only by coming back to that desk. It cannot be done over the telephone.

No. The website offers no games and takes no bets, accounts or payments. It tells you where the door is.

No. Four bath cabinets and twenty-nine rooms is already a tight fit in February.

In the ballroom, seven to ten, except on the forty or so days a year the room is let, when it moves to the reading room.

Louder at night than people expect of a river that size. The river-front rooms get it; the garden side does not.

Four minutes upstream on the left bank. The hot spring is about seven.

Seven spaces in the yard, first come. The street is permit-only and the permits are checked.
