In opera, most people can't see the guest history files.

The hotel should have a general understanding of the personal information and special needs of the guests.

If the guest has not booked a room in the hotel before, for this kind of guest, the hotel will generally make a simple file for the guest when he comes to the hotel to make a reservation, so that the guest can make a reservation quickly. Then, after the guest leaves the reservation department, a detailed guest history file will be established for the guest.
