I found this statement very troublesome and confusing
.
They sell accommodations for business and pleasure travellers at short notice, helping hotels to fill rooms that would otherwise be left empty. They take bookings only within 48 hours of the start of room occupancy.
If a customer booked a room 3 days after it being empty, do we accept this reservation?
Also, this statement introduces a hidden requirement: we need to insert new rooms or update existing rooms provided by the source hotels. Do we need to provide GUI for this requirement?
