What is the process from online hotel group purchase to check-in?

Hello, after you search for a suitable hotel online, first contact the merchant to inquire whether a room is available on the date you need. If a room is available, you can purchase and pay for it. After receiving the group purchase coupon information, contact the hotel. Contact the merchant to make a reservation and inform them of the check-in date and guest information. After a successful reservation, arrive at the hotel on the date of your reservation and pay the deposit for the room to check in
