I opened a room in another hotel and another one in another place. Can anyone find you?

Of course. Hotel rooms are all entered by computer, and you need an ID card to register and check in. When you open a room in another hotel, your personal information will also be entered, so it can be found. No one can find it except the public security organs. This is personal privacy. The case handlers have no due process, and individuals are not allowed to check other people's check-in records casually. You can go directly to the public security bureau to check the room opening records, including the time, date, how many days you stayed, and whether you checked out.
