Please don't disturb the hotel list.

I think you'd better call the hotel guests first, and I'll be at your door soon. I'm in the elevator now, let's see how he answers you. If he wants to say something, you'd better wait for ten minutes or a few minutes, and don't knock. If he agrees, please come in and I'll go at once. You can ask if you knocked at the door when you arrived, although he wrote, Do not disturb.
