Someone was raped in the hotel room. Does the hotel staff have the obligation to open the door to stop it?

Have an obligation. Because hotels have the obligation to ensure the safety of their guests, they should safeguard the personal and property safety of hotel guests, which is a mandatory obligation stipulated by law.

Therefore, when someone is raped in a hotel room, the hotel staff has the obligation to open the door to stop it. Even if it can't be stopped for various reasons, they can call the police to help customers. If the hotel refuses to provide help knowing that its customers are being violated, it will violate the relevant regulations. After the victim is infringed, he can ask the hotel to bear the tort liability, but this liability appears as a supplementary liability after choosing to commit a crime.
