What if the hotel leaks personal privacy? Is it illegal?

It is illegal for a hotel to reveal personal privacy.

First of all, you need to keep evidence, preferably physical evidence. If not, it is ok to have a witness card, but it is best not to be familiar, so the police will trust the witness card more.

Once you have physical evidence and witness, call the police as soon as possible and wait for the police to handle it. Don't fight each other too much. If there is no physical evidence or the physical evidence can't be saved, you can take photos, video or record the conversation between you and the other staff (it should be noted that it is related to the case).

Finally, keep all the valuable information and articles such as the list and materials you have consumed in the hotel and wait for the arrival of the police.
