Why do hotel curtains open by themselves?

Hotel curtains will open automatically for several reasons:

1. intelligent curtain: Some hotels use intelligent curtain. These curtains can be opened and closed through the control panel or remote control in the room. If visitors use the control panel or remote control, the curtains may open automatically.

2. Automatic sensing: Some hotels use automatic sensing curtains. When people are close to the window, the curtains will open automatically to provide better vision and lighting. If the guest is near the window, the curtain may open automatically.

3. Timing setting: Some hotels use timers to control the opening and closing of curtains. If the guest does not control the curtain manually and the timer is set to open the curtain at a specific time, the curtain may open automatically at this time.

In a word, hotel curtains will open automatically, probably because of intelligent curtain, automatic sensing function or timing setting. If you have any questions about the specific situation, I suggest you consult the hotel staff directly.
