Do you need someone from the hotel to take you to the police station to get the proof of accommodation?

Don't. To open an accommodation certificate at the police station, you only need to apply in person and fill in the relevant information according to the relevant regulations. When filling in the application form, you need to truthfully provide the police with information such as name, date of birth, ID number, address on ID card, home phone number, work unit, and two recent bareheaded photos of yourself.
