17 do I need a guardian to stay in the hotel?

Legal analysis: Minors can stay in regular hotels, but they need to bring their ID cards. If you don't apply for or lose your ID card, you can go with an adult.

Legal basis: Article 6 of the Measures for the Administration of Public Security in Hotel Industry stipulates that hotels must register when they receive passengers. At the time of registration, the passenger's identity documents shall be checked and truthfully registered according to the prescribed items. To receive accommodation from overseas tourists, an accommodation registration form shall also be submitted to the local public security organ within 24 hours.
