Can the hotel take pictures with a quilt?

I can't. In a hotel room, there is usually a "Do Not Disturb" sign, which means don't let others disturb you, so as not to let your privacy get out. If it is photographed, it is generally because the hotel has not complied with relevant laws and regulations, or the hotel is improperly managed. Therefore, in order to protect your privacy, it is recommended that you choose a compliant hotel and make sure to turn off your personal equipment.
