What are the skills for booking a hotel by phone?

You don't need to tell them the coupon number and password to make an appointment, but you can ask if there is a group purchase on the date you want to make an appointment.

Just book the hotel and tell the other person the date you want to stay. The check-in time of the hotel is generally after 2 pm, and the reserved room will generally be kept until 6 pm on the day of check-in. It doesn't matter when you arrive in the meantime, so there is no question of saying good early or late. If you need to check in in the early morning, you should make special instructions with the hotel and ask the other party to reserve a room for you.
