How about going to the police station to check my husband's check-in record?

It is impossible to check the husband's check-in record at the police station. According to the relevant public information, the police station cannot directly inquire about the opening record. Check-in information is only recorded in the hotel system and will not be uploaded to the system of the Ministry of Public Security. Unless necessary, the local public security department can retrieve the hotel record information. Hotels or passenger accommodation units must designate special personnel to check and register passenger identity documents, and submit the registration materials to the local public security organs for unified handling.
