Hotel wake up service

When a guest calls to book a wake-up call, it's best to confirm with him. What methods can be used?

I have seen many hotels abroad. They called every five minutes, and after three calls, they opened the door and entered the house without confirmation that the customer had got up.

Because the guest needs a wake-up call, it means that he is in a hurry and can't stay up late. The responsibility of the hotel is to wake up the guests in time.

Therefore, the best way is to put what I said in front of the guest when he booked the wake-up call service, see if he can agree, and tell him that this is your usual practice. If he doesn't agree, do as he says. If he doesn't get up, you can do nothing.
