Ctrip belongs to the hotel channel.

Hotel channel individual guests, guests who come to live in Ctrip, did not book in advance.

Walk in generally refers to individual travelers, referred to as "individual travelers without appointment"; Check-in is the check-in procedure, which is to fill in the check-in registration form for the guest, including some basic information such as the guest's name and telephone number, usually an appointment.

The number of customers in the hotel walk in is generally small, but the hotel must check in whether it is walk in or booking customers. However, because walk in does not have an appointment, if the hotel's housing is tight, the hotel will generally give priority to customers with appointments.
