Stay in front of the hotel

Starting from a five-star economy hotel, arrange room cleaning every day. When you are not in the guest room during the day, the waiter will clean your room. Basically, you can call the waiter to clean at any time. This is their job. Of course, if you don't want to clean during the day, you can hang a "Do Not Disturb" sign on the door so that the hotel staff won't bother you. When you go out at night, you need to clean the room. Put a sign on the door that says "Please clean the room". When you come back, the room will be as clean as new. It doesn't matter whether you hang the "please clean" sign during the day. The waiter will help you clean it!
