What services do those star-rated hotels with such high accommodation fees provide?

Star-rated hotels are all evaluated by the National Tourism Administration, and the software and hardware facilities in terms of service are very good, and the high fees are reasonable! For the simplest example, you can't go to a small hotel in the middle of the night and ask someone to deliver something to you, but a star-rated hotel is manned 24 hours a day, and someone can serve you at any time if you have any problems! And the service attitude is better than ordinary hotels!
