How to book a hotel by phone? I called the hotel directly, and then he asked me your name, check-in time and departure time. That's it. I don't need an ID number.

When you make a reservation, you usually ask your name, check-in and check-out time.

On the day when you really want to check in, you go directly to the front desk and say your name. Then the front desk will help you check the reservation form from the system, then check the check-in time and check-out time with you, then ask you for your documents, pay the deposit and give you the key.
