Housekeeping, maintenance, events, conference rooms and loyalty accounts run beside the stays. Every payment equals the price of its stay, every service charge is its quantity times the service price, every restaurant bill is the sum of its lines, and feedback always names the guest who stayed. Stays run up to a week, and one that checks out the day it checks in is a day-use booking. Rooms are drawn for each stay independently, so two stays can overlap on one room -- a query looking for double bookings will find some, which is what it is there to practise on.", "domain":
